Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a comprehensive coal mine mining device and method based on high-water filling materials, which solves the problem of the existing coal mines after mining. It requires a lot of manpower to carry out tedious demolition and laying work, and the filling work after the device is dismantled is prone to the risk of mine collapse, and at the same time, the filling material will solidify as a whole after being transported underground for a long time, reducing the filling effect

Abstract

The invention discloses a comprehensive coal mining device and method based on a high-water filling material. The comprehensive coal mining device comprises a device chamber and a transmission mechanism, a through opening is formed in the right side of the device chamber, a first sliding groove plate is fixedly connected to the right side of the bottom of an inner cavity of the device chamber, a first sliding block is slidably mounted in the first sliding groove plate, the top of the first sliding block is fixedly connected with a supporting column, and the top of the supporting column is fixedly connected with a bearing beam through a fixing plate. The invention relates to the technical field of coal mining. According to the comprehensive coal mining device and method based on the high-water filling material, the bearing beam is linked with a second motor through a threaded rod, after coal mining is completed, a mining wheel can be retracted into the device chamber through the second motor, meanwhile, through meshing of a gear cylinder and a rack plate, a material spraying pipe extends out of the top, and material spraying and filling is conducted on a goaf; by means of the comprehensive coal mining device, mining and filling can be integrated into a whole.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a comprehensive coal mining device and method based on high-water filling materials. Background technique [0002] The areas where humans mine coal resources in coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig underground tunnels to mine coal. This is an underground coal mine. When the distance is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in China are underground coal mines. The scope of coal mines includes large areas above ground, underground and related facilities. Coal is the most important solid fuel. It is a kind of combustible organic rock. It is a lush plant that grows in a certain geological age. In a suitable geological environment, it gradu...
