Double lane chain filling and backstopping arrangement structure

Abstract

The invention discloses a double lane chain filling and backstopping arrangement structure. The structure comprises a mining lane, a horizontal lane is arranged on the mining lane, a coal pillar is piled in the horizontal lane, a moving seat is arranged in the horizontal lane, one side of the moving seat is welded with two side plates, one side, away from the moving seat, of the upper side plate is welded with a first plate, the top of the first plate is welded with a second plate, a mounting groove is formed in the bottom of the second plate, the mounting groove is internally provided with arotating motor, an output shaft of the rotating motor is welded with a rotating shaft, rotating holes are formed in the tops of the side plates, the rotating shaft is rotatably installed in the rotating holes, two sliding grooves are formed in one side of the moving seat, the sliding grooves are slidably provided with sliding plates, and two gears fixedly sleeve the outside of the rotating shaft.The structure has the advantages of simple structure and convenient use, a pressing plate presses a concrete, a quick-setting agent is sprinkled on the concrete, and the structure effectively improvesthe backfilling efficiency, and can accelerate the solidification of the concrete to meet the use requirements of a user.

Description

technical field [0001] The invention relates to the technical field of mining roadway layout in coal mines, in particular to a double-lane chain filling mining layout structure. Background technique [0002] The mining of coal resources in the past has caused serious subsidence damage and ecological environment problems. Mining subsidence and open-air discharge of coal gangue are the main sources of problems that cause damage and affect the environment of mining areas. The amount of coal pressed under buildings in our country is large, especially in villages, and the amount of coal pressed in some mining areas or minefield villages even exceeds 60% of the total reserves. The problem of coal pressure under the village has become the main problem faced by some mining areas. At present, this problem is mainly solved by the layout structure of double-lane chain filling and mining. The existing double-lane chain filling and mining layout structure needs Coal pillars of a certain...

Problems solved by technology

The problem of coal pressure under the village has become the main problem faced by some mining areas. At present, this problem is mainly solved by the layout structure of double-lane chain filling and mining. The existing double-lane chain filling and mining layout structure needs Coal pillars of a certain size are arranged between the coal pillars and the mining face, so it is necessary to determine the reasonable coal pillar size based on the analysis of the stability of the coal pillars and the surface settlement of the mining. A connection roadway is built between every certain distance of mining and the mining roadway, so it is necessary to determine the reasonable mining distance through the analysis of the impact of mining, but at present, the efficiency of backfilling is low, and concrete is used for backfilling, and the setting is slow, so we propose A double-lane chain filling mining layout structure is used to solve the above problems
