Equipment system for no-roadway no-coal-pillar retained roadway mining method

An equipment system for entry self-retaining mining method, 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 is located in a mining passage and 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;
• working slots are reserved in a top beam of the transition support, working holes or slots are reserved on a top beam of the end support.
