The invention relates to an integrated hydraulic support for mining and filling, which comprises a main support, wherein the main support comprises a base, a top beam, an upright column, a protecting side, a shield beam, a front connecting rod and a back connecting rod; an auxiliary support is arranged at one side of the main support; a pull back chute jack is arranged between the auxiliary support and the main support; the auxiliary support comprises an auxiliary support upright column, an auxiliary support top beam, an auxiliary support base and an auxiliary support connecting rod mechanism; a shield beam side protecting plate is arranged on the shield beam; a back connecting rod side protecting plate is arranged on the back connecting rod; a side protecting plate is arranged on the auxiliary support connecting rod mechanism; and a gob window is hinged along the width direction of the base at the tail end of the base. The invention adopts the main support and the auxiliary support structures; when the main support moves, the auxiliary support can not move and still supports the region to be filled; or when paste is pre-hardened, simultaneously the main support can move forward to support the mining region, thereby simultaneously mining and filling, and improving the working efficiency; and the side protecting plate is arranged behind the main support and the auxiliary support, and the side protecting plate is opened under the action of the jack during filling, and constructs an isolating wall with the side protecting plate of an adjacent support, so that the filling operation can be carried out conveniently.
Description
Technical field: [0001] The invention relates to coal mine machinery, in particular to a supporting hydraulic support, in particular to a mining-filling integrated hydraulic support capable of supporting coal mining and filling spaces. Background technique: [0002] my country is rich in coal resources, fully mechanized mining equipment is mature, and coal mining technology is becoming more and more perfect. With the shortage of energy, the pace of coal mining in my country is accelerating, and more and more mines are facing the problem of resource depletion. The problem is that my country has liberated the "three-down" coal pressing by adopting traditional strip mining, relocating villages, filling mining and other technical measures to improve the coal recovery rate. However, with the increase of mining depth, the increase of village relocation costs and the improvement of filling technology, filling mining technology has become a trend of vigorous development. Most of the...
