Clearance platform AC with adjustable reference 9, 10, 13, 14 ski and conditions of its application from the capacity of the reservoir and the displacement device.

Mining mining unit (module) works as follows.

When used for sinking mines work as follows. Screws module is, receiving rotary motion from the electric motor, when submitting jacks shifting the AFC on the bottom (the harvester is located on the conveyor), through the platform, Samothrace to contact the breast bottom housings of rotary gears, then alternately moved along and across the face with the help of the feeder platform and cylinders rotary screw gears (not shown), wall framing with smooth, with a right angle to the base. In the process of moving the harvester and removal of strips, for example in roof, augers move to the soil layer by simultaneous displacement along the face and so on until the end of the excavation of all stripes over the entire area of the face, then the cycle repeats.

Move the module to the slaughter is carried out jacks advancing shields, performs the functions of the temporary roof support and movement mechanism of the module on the bottom. At the end, for example, conveyor drift when the development system long poles along the strike-reverse module with shields returned to 90 degrees for mounting the camera, the width of which is 1.5-2 times wider than the conveyor drift. Drilling mounting chamber width is also the same module by adding the pans in the AFC downhole portion is at the desired width. After mounting the camera pans of the conveyor, support units deploying to 90 degrees, and the harvester is laid out on the platform in position for cleaning the grooves in the face of reverse swing. With the dam side screws remove rings, preventing in stoping the unloading of the rock mass, and additional screws 36.

Thus achieved the unification of downhole equipment when carrying out excavations on the formation and testing of the reservoir. Reduced at the junction of the two technologies, installation and dismantling, is conducting mining with temporary support in the form of sections of mehrabi, are provided with smooth walls (sides) develop a right angle to the soil excavation.

Folding and unfolding of the mountain harvester is appropriate portable power cylinders relative to the shields and Board production.

To use the module on a powerful layers with increased clearance, when the elements of the body of the combine are located on the platform, the procedure of folding and back halves of the harvester is simplified, as there are on the frame of the platform, with the consequent reduction of the frame or lengthening the amount of insertion, the length of which is determined by the width of the two halves combine folded.

Loading smitten rock mass is like sinking in the pit, and in a clearing, directly auger and rock combine in the AFC. Moreover, when using the AFC in the area of preparatory development (shorter pipeline) loading can be carried out using idle branch pipeline to the location of the cross displacement of both ends of the conveyor, and in its Central part on the gate material handler, in this case, the AFC performs the function of the loading tray digging machine.

In the long lava can simultaneously apply multiple platforms, in addition to rock combine, for example, to install on it the drill carriage, as well as transport installation dismantling tool for assembling and dismantling of downhole equipment (mounting machine).

In addition, in a clearing face can be used concurrently by multiple modules in the frontal mining longwall mining, the number of which is determined by the technical performance of vehicles in a mining face and the conveyor line from the bottom to the unloading of the rock mass on the surface. Provided sammontana and dismantling when peremontazh modules on their own when reciprocating working mine fields.

In a head-on modules ensures completeness of the development of reserves within a mine field because of the mobility of mining mining unit (module).

Thus the om, the equipment at the mine working is also used for sewage extraction. Achieved the unification of downhole equipment in the plane of the layer. Shipping downhole treatment equipment implemented through the use of this equipment when conducting mining. There is continuity of the process of working out the seam the same downhole equipment (module). Decreases the intensity of downhole equipment, the reliability increases with decreasing costs. Maximizes the load on the longwall face at a shortened length of lava, which reduces the emission with decreasing Nude square face with increased security.

The design of the platform can be recommended as a universal vehicle in the wellbore space.

Then cutter-loader moves as idle-running to the end of longwall face, afterwards cutter-loader augers are installed along axis of wells, where at frontal feed of cutter-loader, auger hubs enter wells, and auger blades destroy massif and produce mineral to conveyor with subsequent movement of cutter-loader and formation of new mining strip. In another version of method, cutter-loader changeover is proposed with shuttle method of extraction.

EFFECT: higher efficiency of mining faces operation, simplified technology of second working, reduced costs for equipment, less time spent for auxiliary operations, increased resource of conveyor operation, elimination of multiple bends in conveyor stand.
