摘　　要：鹤岗示范矿区南山煤矿为煤与瓦斯突出、易自燃厚煤层群开采的典型矿井,现主要开采15号和18号煤层,其上、下均无可选择的保护层开采条件。基于分层开采技术,首先对南山煤矿15号煤层进行安全开采,然后将其作为18号煤层的保护层,使18号煤层得到保护和消除突出危险。对18号煤层的保护范围进行了确定,并对15号煤层开采后保护范围的消突效果进行了检验,可为安全开采南山煤矿18号煤层提供理论依据。Nanshan Mine in Hegang Demonstration Mining Area is a typical mine having coal and gas outburst and practicing coal extraction of combustible thick seam group,No.15 and 18 seams are mainly mined at present,and there is no selectable protective seams for extraction above and under them.No.15 seam in Nanshan Mine was first safely mined with slice mining technology and then was taken as the protective seam of No.18 seam,this thus made No.18 seam to be protected and its outburst hazard to be removed.The protective scope of No.18 seam was determined and the outburst removal effectiveness of the protective scope after the extraction of No.15 seam was verified.This study can provide theoretical basis for safe extraction of No.18 seam in Nanshan Mine.
