摘要
Abstract
The 11103 working face is the last longwall fully mechanized mining face delineated by the No.11 coal seam of Ciyaogou Mine.When this working face is pushed and mined to the 920 m position,it is affected by the horst structure and large range and large cross section cutting sandstone,which blocked normal stoping.In response to the actual situation of the 11103 working face,which has a large range and large cross section of gangue cutting,sandstone hard cutting pick that are difficult to break,roof breakage in partical areas that are prone to roof leakage,and relatively long impact time of jumping mining preparation and moving and face overturning,Ciyaogou Mine analyzes the occurrence and changes situation of the working face structure from the detection of the return air channel.The blasting+machine cutting stoping technology is adopted to optimize the labor organization of on-site personnel,compare and analyze the blasting construction effect of gangue deep hole and shallow hole,and formulate adjustment measures such as throwing gangue,roof management and control and others to smoothly pass through the structural area.The practice proves that using shallow hole pre splitting blasting+machine cutting for stoping in the horst structure area can reduce the impact of hard gangue on stoping,ensure mine output and normal continuity,and provide reference for solving related problems in similar mines.关键词
