摘要
鹤岗矿业集团兴安矿三水平北18层地质条件复杂,采用ZF2000/16/24轻型低位放顶煤液压支架的推拉千斤顶联接头、液压系统管路以及安装护煤板等一系列技术措施,实施综放面特殊块段仰斜开采,顺利地完成了该区段煤炭的回采,创造了同样地质条件下煤炭产量的最好水平。
Geological conditions of 3--level North 18 floor of Xin＇ an Colliery, Hegang Mining Industry Group Co. are complex, the paper introduces a series of technical measures such as push--pull jack connection joint in ZF2000/16/24 light type caving coal hydraulic support, hydraulic system pipeline and installation of roadway board, which carries out rise mining of special block in fully mechanized top--coal caving f pletes the section of coal mining, creates the same geological conditions and achieves the ace, successfully combest level of coal production.
