The invention relates to filling and retaining wall of a coal mine conjoined asynchronous support, which can fill and excavate coal at the same time. The filling and retaining wall comprises a fully mechanized mining support, and a filling wall. The top of the fully mechanized mining supporter has a support top beam and the filing wall comprises filing support center empty top cover, a filling support hydraulic pole, a retaining wall soft template chain, a retaining wall soft template plate, an advancing self-moving device, a balance hydraulic pole, a soft template plate suspension beam and a self-moving device chassis; the lower end of the balance hydraulic pole is installed on and rotary connected with the hydraulic pole of the filling support. The left of the advancing self-moving device is installed on the left end of the lower part of the fully mechanized mining support and the right end is installed on the left part of the self-moving device. The soft template suspension beam is fixedly installed under the filling support center empty cover which is on the right side of the filling support hydraulic pole. The retaining wall soft template chain is installed on the soft template suspension beam and the retaining wall soft template is installed on the retaining wall soft template chain.
Description
technical field [0001] The invention relates to coal mine filling back mining pressing coal, in particular to a coal mine conjoined asynchronous support filling retaining wall. Background technique [0002] The coal mine is mined and pressed coal, and the paste slurry is filled to prevent surface subsidence. Filling and coal mining are carried out at the same time, so the filling retaining wall must be used to separate the mining area and the filling area. Since the setting time of the filling body is different from the speed of the shearer, the retaining wall and the shearer must advance asynchronously and at the same speed to meet the requirement of mining and filling at the same speed. The currently used isolation methods include capsule-type one-time consumption filling; template and mechanical retaining wall. Both the bag type and the formwork consume a lot, resulting in obvious waste, the volume of the filling retaining wall is too wide, the space of the roof is larg...
