Abstract:
An equipment system for a self-retaining mining method mainly comprises a transition support, an end support, a following support, and a fast-retracting support. Working face gateroads do not need to advance in mining, and a coal mining machine may be used to cut a neat coal wall at the end of a district. The entry rib is automatically formed after roof caving, thus forming a gateroad in a re-mining process. The coal mining machine is under digital control when its end cuts the coal, automatically enabling the end to laterally cut the coal wall to form a vertical straight line, which is used as the entry rib of the gateroad. A scrapper conveyor works in coordination with an arc-shaped coal grabbing plate of the coal mining machine to clean up float coal at the end as much as possible.

Claim (Index 1):
An equipment system for entry self-retaining mining method, with the equipment system, no-entry non-pillar self-reserved entry mining is carried out in a district, wherein, the equipment system comprises a transition support, an end support, a following support, a retracting support, a cutting device and a coal mining system; the coal mining system performs coal mining work in a mining passage that has an outer end connected to an upper gateroad and an inner end connected to a lower gateroad; the lower gateroad is an entry retaining area, the upper gateroad and the lower gateroad are substantially parallel to a mining direction of the coal mining system, and an area between the rear side of the mining passage and the outer side of the entry retaining area is a pressure release area at a gob; the transition support, the end support, the following support and the retracting support telescopically support a bottom rock mass and a top rock mass of the district; the transition support is positioned between the mining passage, the pressure release area at the gob and the entry retaining area; the end support is positioned within an overlapped area between the mining passage and the entry retaining area there are multiple sets of the following supports with at least two in each set, and the following supports are positioned in and arranged in turn along the entry retaining area; the retracting support supports the mining passage; and as the coal mining system is advanced forward for mining, the mining passage is advanced forward, and the transition support, the end support, the following support and the retracting support move forward along with the mining passage;\n a longitudinal cutting operation is performed on the top rock mass along a boundary line between the entry retaining area and the pressure release area at the gob by using the cutting device, and thereby the top rock mass collapses to form the pressure release area at the gob.
