Characteristics and photos of the DML drilling rig and its modifications: LP 1200 and SP

The equipment of a drilling rig depends on the conditions in which it will work, the purpose of the well, the properties of the soil and the drilling method.

Manufacturer and purpose of DML drilling rigs

Founded in 1873 in Stockholm, it produces equipment for the construction, drilling, and railway industries. The constant pursuit of perfection has made the equipment from the Swedish brand unsurpassedly effective.

The four main industries that Atlas Copco focuses on are:

• equipment for mines and drilling;
• mobile equipment for construction and energy generation;
• compressors;
• tools for industry.

The Atlas Copco DML series of drilling rigs is designed for rotary drilling.
The depth of the wells is in the middle range. Drilling that is carried out using these installations:

• rotary - rotational drilling, when a bit (a tool for breaking rock) deepens the depth of a cylindrical well; rotation is transmitted to it from the rotor through a column of drilling pipes;
• the rotor receives rotation from the engine;
• drilling using a down-the-hole hammer - multi-pass.

Design Features

DML units are mobile equipment; they are equipped with crawler tracks and hydraulic drive. The upper hydraulic drive is a development designed for drilling explosive-type wells up to 53.3 meters deep. When replacing the pipe, a depth of 62.5 meters can be achieved. For standard and additional pipes (9.15 and 10.7 m), additional carousels with different volumes are provided.

During drilling, a load of 267 kN is created on the bit. Additional equipment makes angular drilling possible when the column deviates from the vertical by 30 degrees or more.

Advantages:

• the ability to lift a column with a carousel, which contains six drill pipes, in less than a minute;
• the operator remotely, while in the cabin, changes pipes and secures the carousel; The cabin equipment is FOPS certified;
• visibility from the cabin allows you to control the operation of the rotor;
• the high-pressure compressor is equipped with an on-off system that eliminates the load during work not related to drilling;
• this simplifies startup, saves energy, and extends the life of the compressor;
• The DML drill rig is configured for high or low pressure drilling.

Small-sized water drilling rig: mini

Country houses and cottages are not a reason to give up comfortable living conditions. Therefore, the presence of an autonomous water supply in the absence of a centralized one becomes the first task of the owner.

But even if water is supplied to the site from the main line, its quality can be so poor that your own source becomes a necessity no longer for comfort, but for health.

And to drill a well, you just need to purchase the necessary tool - this is a small-sized water drilling rig.

Advantages of MGBU

Small MGBUs are excellent for drilling water wells in private households

Large equipment can easily drill an artesian well, a mine for the extraction of oil, gas and other minerals, but small MGDUs are excellent for drilling water wells in private households. And, by the way, the purchase of such equipment will not particularly affect the family budget, if your site is not the only one in the area, then the drilling machine can generate income from rental.

The installation has many advantages:

1. Mobility and compactness of equipment;
2. at the same time, the MGBU for drilling water wells is easy to use;
3. drilling will not harm the landscape of the site, since the well is drilled using small-sized equipment;
4. MGBU is very convenient for working in confined spaces and allows drilling wells in garage basements and outbuildings;
5. Dismountable equipment is extremely convenient to transport and does not require the use of special equipment for installation/dismantling or transfer;
6. The MGBU receives power from a standard 220-volt outlet, but if necessary, can operate from a mobile power source;
7. MGBU works quickly, without failures (there is simply nothing to break), allowing you to quickly provide water supply to a country house.

Description of MGBU

MGBU is lightweight, mobile, and has expanded functionality

With its light weight, mobility, expanded functionality in limited spaces, and affordable cost, the drilling rig has the following set of elements:

• mud pump for injection of solution;
• swivel to ensure free rotation of the drill, reliability of the entire structure;
• winch – a lowering/lifting tool that ensures the performance of technological operations;
• the hoist system lifts and supports the weight of the drill;
• The circular design has the function of preparing and supplying the solution.

Design features distinguish between drilling methods using small-sized installations: auger, impact, with flushing.

Percussion drilling method

The winch lifts the pipe, then lowers it, loosening the soil, which is pulled up by a bailer

It is the simplest and most accessible. The MGDU for drilling wells is complemented by a metal pipe with a bailer. The winch lifts the pipe, then lowers it, loosening the soil, which is pulled up by the bailer. Plus, the end result is a practical, good underwater mine. Minuses:

• low speed;
• mandatory lining of the mine with large-section pipes;
• when encountering quicksand, the mine will simply collapse.

Auger drilling option

Used for drilling wells in sand and other light soils

It is used for drilling wells in sand and other light soils. Functionally, the shaft is drilled using a rotating auger, which lifts loose soil to the surface. The advantage is that all processes can be carried out point-by-point and without the use of power. Disadvantages - mandatory removal of the auger for cleaning.

It is very convenient to use the auger option for drilling wells in limited space. Thanks to the point notching of the end of the drill, which can be made pointed, and the small turning space of the spiral, the shaft is not wide, which is beneficial when installing a water supply system, for example, in the veranda of a private house.

Drilling with flushing

This is one of the most productive ways to drill water wells

This is one of the most productive ways to drill water wells. The mini drilling rig can reach speeds of up to 10 m/hour, which is significantly faster than any other drilling method. Well flushing can be done using both direct and reverse methods.

Direct - this is when the solution is fed directly along the rod, washes out the soil and transfers it to the surface. Reverse - the solution is fed into the mine, pumped out along with the soil through a pump.

The use of small-sized installations for drilling water wells is also justified in terms of economic indicators - the cost of wells is low, and given that such a mine lasts at least 5-8 years, the payback of the equipment is extremely fast. There are many positive aspects:

• drilling equipment can be disassembled, removed and used for its intended purpose at any time;
• using MGBU, shafts are drilled for a pile foundation;
• You can always drill a mine for water in any convenient place.

The only disadvantage of small-sized installations for drilling water wells is the ineffectiveness of their use on heavy soils; the equipment has no other disadvantages.

Drilling a well with a small-sized rig in the Moscow Region

offers its clients in Moscow and Moscow Region fast, inexpensive, convenient and effective small-sized drilling of water wells on favorable terms.

We have trained engineering and drilling specialists, modern technologies, high-quality drilling rigs and construction materials for equipping wells and autonomous water supply systems for dachas, private houses, cottages and small businesses.

Drilling water wells with a small-sized installation is a modern way of creating water wells on small plots of land, where there is not enough space to equip a large well and there are cramped conditions for the operation of drilling equipment.

A small-sized drilling rig is a compact (can fit into gates, fence sections and doors), lightweight portable/self-propelled unit that does not require a massive chassis and a large area for drilling operations. At the same time she:

• performs drilling using several methods (auger/percussion/rotary);
• can drill wells directly under a house or technical room;
• quickly drills wells up to 100 meters deep with smooth walls (high speed due to the rapid expansion of drill rods and the use of flushing solution);
• works in any weather conditions (-20+40С);
• can connect to nearby power networks;
• serviced by 2-3 specialists;
• does not spoil the surrounding landscape and does not create dirt.

The best option is to drill an Abyssinian well of shallow depth, for which the installation requires several square meters of working area and a couple of meters of height. An important point: drilling wells with a small-sized drilling rig has a minimum cost and is maximally accessible to a wide range of private customers.

At the Berezovsky open-pit mine, 2 WORLD production records were set.

the Epiroc (Atlas Copco) DML-1200 drilling rig drilled more than 48 thousand linear meters of wells in a month.

The rod of the DML-1200 drilling rig makes up to 1500 revolutions per minute and plunges into the ground to a depth of 9 meters. At this time, there is minimal noise in the driver's cabin. It is equipped with the latest technology - it has air conditioning, a ventilation system and reinforced glass. But there is no need to be afraid of dust or rock fragments - the drilling site is securely covered with a special curtain. A few minutes and the mast of the drilling rig rises, revealing a small-diameter well. The cutting team made more than 5 thousand of these in a month.

Evgeny Bukalov, head of the branch of Mining Solutions in Kemerovo:

— “The Mining Solutions company, as the official supplier of this equipment in Russia, confirms that this is indeed a WORLD RECORD: a daily world record with a result of 2088 linear meters and a monthly world record of 48021 linear meters.”

The new drilling rig went into production this spring. The world record is the result of a collaboration between the customer’s professionalism and the coordinated actions of the Mining Solutions service department.

There are already 20 such drilling rigs, more than half are working at the Berezovsky open-pit mine. They also provide the highest performance indicators. This world record for drillers has become the seventh one recently set by Stroyservis miners.
