Description

The present invention provides a method for mechanically punching holes in utility minerals using remote disengagement devices.

The punching of the ee has so far been carried out largely with the disintegration of the coal cell jacks or by the aid of blasting. In bores with a greater bow, the mining compartments must be set up properly connected to the climbing and transport compartments. Separate ventilation must be provided in the perforations with steel sheet lutes. The classic method of driving is very laborious, laborious, lengthy and dangerous. Methane builds up in the face; A very laborious operation is the ultimate method of transporting all material and forced into the advancing face, and the ripping itself in the inclined or vertical part is laborious and dangerous. The low work performance and insufficient excavation procedures of such mines do not meet current technical and economic requirements. In the deposits of utility minerals with the risk of mining shocks or bursts of coal and gases, water spills, high gas content and the like, a reliable method of protection of workers has not been established. Known and used measures, such as drilling boreholes and the like, do not solve this problem quite effectively and, moreover, reduce the technical-economic parameters of the stamping.

These drawbacks are eliminated by the invention, which consists in the fact that between the lower and the upper corridor is made in the utility mineral borehole, which is pulled through a loop of cutting, endless and driving chain, wrapped around the chain sprockets with the cutting system.

201 149 ml blades, and On the one hand through the pulley of the driving and tensioning station, the cutting and endless and driving chain cuts in the borehole and at the same time rotates the sprockets e cutting blades that cut the rectangular bore hole in the bore. into the well.

The proposed method of driving the river primarily safety, eliminates the possibility of accumulation of methane, because through the borehole passes through the wind current. The use of lutes is eliminated. The new method eliminates blasting and overhead transport of material, production of the extracting section, and more laborious overhead. First of all I deal with safety, hygiene and culture of mining work. Significantly reduces puncture punching time and increases performance to eliminate physical exertion by workers.

This method provides a completely new and effective assurance of the safety of workers working in seams dangerous by bursts of coal and gases, hot shocks, and the like, since it enables the uncoupling operation to be carried out without the presence of a crew in the face. A further advantage of the design is, in particular, that it allows for the punching of the punching at all and the simultaneous building, which represents a continuous punching 8 by eliminating the disadvantages of the classical methods. It enables excavation during through-ventilation through a borehole, which is constantly extended by the cutting chain, thereby ensuring the throughput of the borehole. The damping eliminates the installation and transportation of lutes, the risk of gassing the face e. The invention permits such narrower perforations to be carried out, since there is no need to provide a mining separation in a semi-steep and steep bearing, which in turn represents a cost saving of the lumber, including the cost of transporting them. Said constriction of the piercing is essential for increasing its stability, since it reduces the damaging effect of mountain pressures ee by reducing the open space. Increases the service life of punctures without the need for laborious maintenance. We also reduce not only labor and excavation costs, but also excavation time, which in turn has no impact on quicker readiness for mining.

The drawings show schematically an example of a method of mechanically punching the top punch of FIG. 1 and the broken punch of FIG. 2 in a steep seam.

First, a borehole is drilled between the lower class 2 and the upper class 6 in the utility mineral which is expanded below the upper class 3 and inserted into the cutter 5. The cutting unit 6 consists of a chain wheel system 6 β cutting blades mounted on a spacer structure. working attitude £. A loop of the cutting endless and driving chain 4, wrapped around the chain sprocket assembly 6e by the cutting edges, is guided through the bore 13 through the pulley of the drive station 14, through the chain pulleys 13. Cutting device 5 ee suspended! The driving and tensioning stations 14 move the loop of the cutting endless and driving chain 4, thereby imparting rotation to the sprocket assembly 6e with the cutting edges. Said chain 4 extends the orifice of the borehole 11, the pulp at the same time with a plurality of falling commercial minerals and ensures the continuous throughput of the borehole. In this case, the sprocket assembly 6 e extends the borehole 1 into the rectangular borehole profile. The process of cutting the machine 5 proceeds by its own weight and by pulling the cutting endless and driving chain 4 through the driving and tensioning station 14. Stabilizing and regulating the cutting machine 5 for remotely controlling the disintegration of the utility mineral in the well 1 secures the locking winch 10 mounted on In the final driving of the piercing 7 ee from the working command 8, it builds up the reinforcement 9.

The method of mechanically punching the punch can be carried out as shown schematically in FIG. 1. In this method, the drive and tensioner of the chain block station 14 is placed on the top class 3 and suspended on the loop of the cutting endless and driving chain 4 ss. 5. The topcoating process is essentially the same as in the excavation, with the difference that the entire area of the piercing hole 7 is first used without the presence of the crew. Only then is it installed from top to bottom.

This method is particularly advantageous in seams with the risk of bursts of coal and gases, or the risk of mountain shocks, since the crew is out of the danger zone on adjacent lower and upper classes 2, 3 for the duration of the exploitation process.

Other options It is embossed in a flat bearing, where the disconnect operation can also be performed without the presence of the crew. In this case, the excavation of the mines and the building-up are carried out in the usual manner. The invention can also be used in the mining of utility minerals by tunneling, pillaring or blocking, in a top or down way, with the possibility of abandoning the building, i.e., securing the occupied space, without the presence of a permanent crew.
