Example Embodiment

[0010] The method of moving the fully mechanized mining face quickly under special geological conditions is realized by the following steps: 1. Push the working face to the stop line position 1, and excavate the new (jump face) cut 2 (that is, bypass the collapse column in advance) , Faults, etc. to excavate a new working face); in the actual implementation, the new cut-off cut has a clear width of 7.5m and a clear height of 2.95m, and the conditions for equipment installation are available. After the working face is pushed to the position of the scheduled stop line, the old cut-off cut will be expanded in time to support it, and the conditions for equipment removal are available. 2. Harden the ground of the new cut 2, the old cut 3 and the roadway 4 connecting the new and old cuts (such as laying concrete or other materials); 3. Along the old cut, the road along the road, and the new cut Lay wooden sleepers and add a steel sleeper 5 every 1.5 meters. Lay steel rails 6 on the s...

Abstract

The invention relates to a method for moving a fully mechanized mining face, in particular to a method for quickly moving the fully mechanized mining face under the special geological condition, and solves the problems of low speed and efficiency of the conventional method for moving the fully mechanized mining face under the special geological condition. A hydraulic bracket is directly dragged on a steel rail; in order to adapt to direct hauling, the structure of the rail is improved and optimized in modes of hardening the ground, adding a steel sleeper and a steel guardrail, and the like; and other fully mechanized mining equipment except the hydraulic bracket still adopts the conventional moving method. The hydraulic bracket is directly hauled, so that processes of feeding an empty vehicle, turning the vehicle, loading the vehicle, discharging the empty vehicle and the like in the conventional moving method are saved; therefore, the fully mechanized mining face is quickly moved under the special geological condition, a large amount of auxiliary work time is saved, and production efficiency is improved; meanwhile, vehicle deviating and rail separating accidents which possibly occur in the conventional moving method are avoided to a certain extent, and operation safety is effectively improved.

Description

technical field [0001] The invention relates to a method for moving a fully mechanized mining face, in particular to a method for quickly moving a fully mechanized mining face under special geological conditions. Background technique [0002] After the mining of the fully mechanized mining face is completed, it is necessary to move to the next fully mechanized mining face, and move the shearer, front slide, back slide, hydraulic support and other equipment of the fully mechanized mining face (also known as the old cutting hole) that is about to be mined. To the new fully mechanized mining face (also known as the new cutting eye). At present, the moving method of the fully mechanized mining face under normal conditions is as follows: 1. Lay wooden sleepers along the old cut, along the channel roadway (that is, the roadway connecting the new and old cut), and the new cut, and lay steel rails on the sleeper, that is Lay a track connected by a trough lane between the old and ne...
