Abstract

The invention provides a mechanical continuous mining method for a roadheader, which relates to the technical field of mining, including: a mining layer and an extra-vein roadway; the mining layer and the extra-vein roadway are connected; Road and support column; a support column is set between each adjacent two mined access roads, the access road communication channel is set on the support column, and the two ends of the access road communication channel are respectively connected with the adjacent two mined access roads. The road is connected, so that the roadheader can enter the adjacent mining road from one mined road. When the roadheader drives to the specified position in the first mined road, it can directly enter the adjacent road through the road connection channel. The second mined road continues to be excavated, and the support and feng shui pipe erection operations are performed on the first mined road, so that the roadheader does not stop during the support and feng shui pipe erection operations, which solves the problem of low mining efficiency of the current roadheader. The technical effect of continuous work of the roadheader and high mining efficiency is realized.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a mechanical continuous mining method of a roadheader. Background technique [0002] Coal mines have achieved continuous mining through mechanization. In non-coal mines, it is the development direction of hard rock mining technology to practice the mechanized mining method of continuous cutting to replace the traditional way of blasting. 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 to the required distance of safety, the cantilever roadheader needs to withdraw from the road, and the construction personnel enter the road to perform support and ventilation pipe erection operations. [0004] However, when the construction personnel enter the road to p...
