摘    要:小煤矿在我国西部约占90%,必须执行安全生产的方针规范采煤方法。本文在有效改造原则的基础上,从榆林地区煤炭赋存、开采技术现状出发,提出了长壁留煤柱支撑法开采和长壁布置现代房柱开采两种采煤方法,以及相应的技术特征,供改造参考。指出其关键技术是合理设计区内支撑煤柱和区域隔离煤柱,在采出率提高的同时,必须实施监测,防止大面积顶板事故监测

关 键 词:煤矿开采方法  顶板事故  面积  防止  采煤方法  安全生产  改造原则  榆林地区  开采技术  房柱开采  隔离煤柱  合理设计  关键技术  事故监测  小煤矿  支撑法  内支撑  采出率

Regulating small coal mine mining method and preventing large area roof accident
Authors:SHI Ping-wu  LIU Yang
Abstract:Small coal mine accounts for 90% in west china,therefore the policy of the safe production must be carried out for regulating mining method.Basing on reforming minimg method effectively and setting out from coal deepness and condition of mining technology in Yulin latitudes,the article puts forward two types of mining method:one is longwall remaining coal pillar support mining,the other is longwall modern room and pillar mining,as well as corresponding technology character.They can provide reference when reforming mining method.The article points out the key technology is to design regional support coal pillar and area isolated coal pillar.Moreover,while improving the rate of mining coal,roof must be monitored in order to prevent large area roof accident from occurring.
Keywords:small coal mine  mining method  isolated coal pillar  coal pillar  large area roof accident
