End slope coal bed remote control excavating mining method

Abstract

The invention provides an end slope coal bed remote control excavating mining method, which belongs to an end slope residue coal resource extraction method and is used for open pit coal mine end slope and hillside outcrop and shallow surface coal bed mining. A coal mining system adopts a remote control excavating machine system, which comprises an excavating machine and a remote operating and control room, wherein operating and control equipment consists of three parts including a mining flameproof excavating machine electric control box, an excavating machine electric control box and an operating table; the operation function of long-distance wired control is realized; the man-machine separation is realized; and during the coal mining, people operate in a safe operation room. The main mining flow process comprises the steps of cleaning preparation, initial stage mining roadway pit selection, excavating and coal cutting by the excavating machine, coal loading by the excavating machine, belt extending, outward coal conveying by a belt, pile pouring by a loading machine, laneway exiting after coal excavating to a preset position, equipment withdrawing, overhauling, and preparation again for next roadway pit extraction. The end slope coal bed remote control excavating mining method has the characteristics that the coal resource extraction rate improved; the production process is simple, safe and efficient; and the production cost is low, and the like. The safe and efficient mining of open pit coal mine end slope remained coal resources is favorably realized.

Description

technical field [0001] The invention relates to a method for recovering end-side residual coal resources, in particular to a method suitable for mining end-side residual coal, hillside outcrops and shallow surface coal seams in open-pit coal mines. Background technique [0002] In coal mine production, since both open-pit and underground mining have their own specific scope of use, many coal resources left over from open-pit mining cannot be efficiently recovered. For example, coal production bases such as Ordos in Inner Mongolia and Shenfu in northern Shaanxi have a large number of open-pit coal mines, hillside outcrops, and shallow surface coal. In the past, due to the constraints of mining technology and economic benefits, these resources were mostly abandoned or used as low-recovery room pillars. The development of conventional coal mining method not only causes waste of resources, but also causes hidden dangers such as spontaneous combustion of coal seams, destruction o...

[0002] In coal mine production, since both open-pit and underground mining have their own specific scope of use, many coal resources left over from open-pit mining cannot be efficiently recovered

For example, coal production bases such as Ordos in Inner Mongolia and Shenfu in northern Shaanxi have a large number of open-pit coal mines, hillside outcrops, and shallow surface coal. In the past, due to the constraints of mining technology and economic benefits, these resources were mostly abandoned or used as low-recovery room pillars. The development of traditional coal mining method not only causes waste of resources, but also causes hidden dangers such as spontaneous combustion of coal seams, destruction of surface vegetation, and large-scale subsidence of residual coal pillars.

In addition, in many cases, there are disadvantages such as high labor intensity, low mining continuity, and many safety hazards due to the small working space and no support in the roadway mining
