Double-wing continuous coal mining technique for open-pit coal mine

Abstract

The invention relates to a double-wing continuous coal mining technique for an open-pit coal mine. According to the storage distribution and geological characteristics of the open-pit coal mine, firstly a plurality of mining areas being 2000*90m are designated, then a plurality of fan-shaped width mining areas are designated in the mining areas, and digging, crushing, transshipping and conveying equipment is laid in each width mining area according to a way of forward mining in a main lane and oblique fan-shaped mining in left and right wing lanes to form standardized cycle operation. According to the double-wing continuous coal mining technique, the process is advanced, the ancillary working time is shortened, the reciprocating motion times are reduced, the equipment working for cycle operation can be fully utilized, and the safety of coal mining is improved, so htat the double-wing continuous coal mining technique for the open-pit coal mine is very ideal.

Description

technical field [0001] The invention relates to a double-wing continuous coal mining process in open-pit wide mines, and belongs to the technical field of coal mining equipment applications and coal mining methods. [0002] Background technique [0003] The mining of open-pit coal mines mostly adopts the method of single-bucket excavation, truck transportation, centralized crushing station crushing, and belt conveyor transportation, that is, single-bucket excavator excavates on site, trucks transport to the crushing station for crushing, and then transport to the Outside the stope, into the coal bunker, this traditional coal mining process makes the truck transportation channel occupy a large area, the centralized crushing station is difficult to move, takes a long time, the coal mining efficiency is low, the safety is poor, and the environmental pollution is serious, resulting in coal mining The cost has been greatly increased, and the thin coal seam has been discarded, re...
