Abstract

The invention provides a gangue filling underground system, which belongs to the technical field of gangue backfilling underground and comprises a loading chamber, a feeding assembly and a buffer assembly. The loading chamber is located under the ground, the bearing hole is communicated with the loading chamber through the ground, a gangue sliding frame is arranged in the loading chamber, the bearing hole extends into the loading chamber and is provided with a feeding assembly, the feeding assembly comprises a sleeve and a material conveying pipe detachably arranged in the sleeve, and the diameter of the material conveying pipe is smaller than that of the sleeve. A buffer assembly is arranged in the loading chamber, preset distances are arranged between the buffer assembly and the conveying pipe and between the buffer assembly and the gangue sliding frame respectively, the buffer assembly comprises an arched beam and a buffer fixedly connected to the arched beam, the top of the buffer is of a conical structure, and the buffer and the central axis of the conveying pipe are linearly distributed. The system not only can avoid the formation of a large amount of flying dust, but also can avoid the situation that the hole of the feeding well is easily blocked due to gangue accumulation.

Description

technical field [0001] The present application relates to the technical field of gangue backfilling underground, and in particular, relates to a gangue filling underground system. Background technique [0002] When mining coal, due to mining conditions and technical limitations, the mined raw coal will be mixed with certain gangue. In order to avoid gangue affecting coal quality, it is usually washed in a ground coal washing plant, and the washed gangue is processed uniformly. The efficient and environmentally friendly gangue treatment plan is underground backfilling, that is, the ground gangue is crushed and transported to the underground, and the space formed by the roadway and goaf is used for backfilling. This can not only prevent the risk of spontaneous combustion of gangue piles, the emission of harmful gases, collapse and explosion caused by the accumulation of gangue piles on the ground, but also can effectively support and fill the underground roadway after backfill...
