Types, specifications, repair, and maintenance of drilling rigs
Drilling rigs. Core drilling machines. Performance indicators of the main types of drilling rigs. Migration equipment. Equipment for soaking, flushing, and screwing rock using impact and vibration. Drilling is the process of breaking up soil, which creates a cylindrical cavity in the aboveground massif while removing the debris to the surface. Large boreholes, called wells, exist, with a diameter of up to 75 mm and a cavity depth of up to 9 m. During construction, drilling is used for engineering and geological surveys, for installing poles, road signs, permanent installations, drilling and drilling devices, anchors (power lines), for installing water pipes and water supply systems, and for blasting excavations.

Types of drilling rigs
the purpose of an excavator is to develop a blasthole during mineral extraction. Rigs are classified by a number of parameters, such as drilling method, drive type, penetration depth, type, execution technique, etc. For proper operation of the equipment, it is important to remember that high-quality drilling rigs are essential.

Since ancient times, people have been engaged in earthworks. Today, the volume of such operations is simply enormous (construction, haulers, roads). Performing all Today, drill bits are the most common tool in mining operations. They are an effective crushing tool used in conjunction with rotary drills. The name comes from the component of the same name—the roller bit, a grinding tip with teeth of varying shapes and sizes, or a tungsten carbide pin. These units are powerful enough to handle even the most complex monolithic structures
drilling Rigs: Technical Specifications
The following parameters are generally accepted by which drilling rigs are evaluated:
We will describe the design of excavators for hard and soft rock mining—the criteria by which they are selected, and the role the nature of the work involved.
- Excavation diameter (max. 900 mm);
- Drill string impacts per minute (max. 50);
- Drilling height above the face (max. 1 m);
- String weight (max. 2500 kg);
- Total unit weight (max. 13, 000 kg);
- Electric motor power (max. 54 kW/hp);
- Engine speed (max. 735 rpm);
- Mast height (max. 16 m);
- Load capacity (max. 25, 000 kg).
The appropriate excavator specifications are important when selecting the right equipment. Standards ensure the ability to drill holes and lift fractured rock to the surface.
This method is also designed to clean holes and penetrate loose, unconsolidated rock and quicksand. While drilling, it is necessary to establish borehole walls if the rock is unstable: every 20-100 cm (depending on the rock type), the excavator must clear the voids of rock debris. A special “plate” is used for this purpose, which allows for ascent and descent into the working face.
The main criterion for selecting an excavator’s weight is the hardness of the rock being processed. The harder the rock, the greater the weight and power required for the equipment to operate effectively. As for the impact frequency, it should increase when drilling softer, layered, and fracture-prone rocks and decrease when drilling hard monolithic rock. Also, depending on the reinforcement, different bit designs are used—flat (solid) or double-turret.
To operate a drilling rig, you will need a license of a certain category. You can train at a special school and obtain a license only by passing an exam. Some people believe it is easier to buy a drilling rig license and obtain a driver’s license without taking the exam, but in this case, criminal liability must be kept in mind.
