根据苏联露天开采研究所井口开采研究室的建议,在阔尔金斯卡娅、库普良尔斯卡娅、巴土林林斯卡娅三个矿井(开采厚煤层的矿井),从1972年开始研究和推行了无煤柱开采技术。根据沿空巷道矿压显现和岩体应力研究结果,于1978年制定出有自燃倾向煤层无煤柱开采工艺系统,总共有八种系统,可用于各种矿山地质条件,其中得到核准的五种方案如下:
According to the suggestion of the Soviet Open-pit Research Institute of Wellhead Exploitation, three mines (mines that mine thick coal seams) at Kurskaya Kaya, Kupliangskaya, and Basulin Linskaya, from 1972 Started research and implementation of non-pillar mining technology. According to the research results of underground pressure and rock mass stress in gob-side entry roadway, in 1978, a non-coal pillar mining technology system with spontaneous combustion tendency was developed. There are altogether eight kinds of systems which can be used for various mine geological conditions, of which five are approved The program is as follows:
