Roadway intelligent gangue filling machine and filling method

Abstract

The invention provides a roadway intelligent gangue filling machine and a filling method and relates to the technical field of gangue filling. The filling machine comprises a top plate fixing device,a hauling rope, a filling round-bottomed bucket, a first electric drum, a second electric drum and a position sensor. The top plate fixing device is arranged on a top plate and comprises a pulley anda tensioning device. The hauling rope is wound around the pulley. The filling round-bottomed bucket is arranged on the hauling rope. The two ends of the hauling rope are fixed to the first electric drum and the second electric drum correspondingly. The position sensor determines the distance between the round-bottomed bucket and the pulley as well as between the round-bottomed bucket and the firstelectric drum. In the gangue filling process, by means of the filling round-bottomed bucket, filling materials in a roadway are directly piled, the first electric drum and the second electric drum are utilized for pulling the filling bottom-round bucket to achieve automatic piling and discharging, and then piling of the filling materials within a certain distance is achieved. The technical problem that in a wall type exploiting system, especially in the short roadway, construction of a large filling tool is inconvenient is solved. In addition, the machine has the advantages of being flexibleto use, high in working efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of gangue filling, in particular to a gangue filling machine suitable for wall system mining and a filling method using the filling machine. Background technique [0002] Filling mining is an effective method to solve the problem of leaving a large number of coal pillars in mining and avoiding surface subsidence. Therefore, in order to effectively control surface subsidence, reduce the retention of coal pillars in the mining process, and improve the recovery rate of coal mining, it is necessary to construct underground filling. Paste filling has disadvantages such as high cost and complex equipment; non-paste filling near-horizontal coal seams still need to solve problems such as unreasonable filling process and insufficient filling strength. In the process of wall mining, especially the filling in the short roadway of wall mining, it is not suitable to use large-scale filling equipment in this process, and ...
