Abstract

The invention provides a mechanical continuous mining stope structure of a heading machine and a mining method of the mechanical continuous mining stope structure, and relates to the technical field of mining. The stoping layer is communicated with the outside-vein roadway, and the stoping layer comprises an access connection channel, a stoped access and a supporting column; one supporting column is arranged between every two adjacent mined access roads, the access road connection channel is arranged on the supporting columns, and the two ends of the access road connection channel are communicated with the two adjacent mined access roads respectively, so that the heading machine can enter the adjacent mined access road from one mined access road, and the heading machine can enter the adjacent mined access road from the other mined access road. When the heading machine is tunneled to a specified position in the first mined drift, the heading machine directly enters the adjacent second mined drift through the drift connection channel to continue to tunnel, and the first mined drift is supported and the wind-water pipe is erected, so that the heading machine does not stop during the supporting and wind-water pipe erecting operation, and the heading machine is not stopped during the supporting and wind-water pipe erecting operation. The problem that an existing heading machine is low in mining efficiency is solved, and the technical effects that the heading machine works continuously and is high in mining efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a roadheader mechanical continuous mining stope structure and a mining method thereof. Background technique [0002] Coal mines have achieved continuous mining through mechanization. In non-coal mines, the practice of continuous cutting mechanized mining methods to replace the traditional way of blasting is the development direction of hard rock mining technology. The cantilever roadheader mechanical mining method has been applied in the non-coal mine mining of ore rock crushing, unstable sloping to steeply sloping thick and large ore bodies. [0003] During the mining operation of the existing cantilever roadheader, when the machine falls into the mine at a safe distance, the cantilever roadheader needs to withdraw from the road, and the construction personnel enter the road to carry out support and ventilation pipe erection operations. [0004] However, when the construction pe...
