摘 要:煤炭开采过程中,由于强矿压的作用会引起各种复杂的动力现象,影响采矿作业的正常进行,威胁煤矿的安全生产,探索新的技术途径控制特厚煤层开采中强矿压难题势在必行。以大同塔山煤矿为工程研究对象,运用三维计算机模拟、实验室研究和工业性试验研究,分析多煤层开采时,解放层山4#煤层采动后对3-5#煤层开采的影响,研究利用解放层开采区域治理大结构顶板强矿压技术,并分析该技术的适用条件和作用,获得基于解放层开采区域的特厚综放大结构强矿压顶板运动规律、矿压显现规律及控制措施等,为特厚煤层综放大结构顶板强矿压开采支护方式选择、巷道布置形式、支架选型以及支架控制技术参数的确定提供依据,为类似条件下的煤层开采开创了新的技术途径。In the process of coal mining,due to the action of strong mine pressure,various complex dynamic phenomena will be caused,which will affect the normal operation of mining operations and threaten the safe production of coal mines.Explore new technical ways to control the strong mine pressure in the mining of extra-thick coal seams.Must do.This paper takes Datong Tashan Coal Mine as the engineering research object,uses three-dimensional computer simulation,laboratory research and industrial test research to analyze the influence of the liberated layer NO.4coal seam mining on the NO.3-5 coal seam mining when multiple coal seams are mined.Utilize the technology of controlling large structural roof strong pressure in the liberated layer mining area,and analyze the applicable conditions and functions of the technology,and obtain the law of strong mining pressure,the law of mining pressure appearance and control measures based on the extra-thick and comprehensively enlarged structure of the liberated layer mining area.It provides a basis for the selection of the support method of the super-thick coal seam's fully-enhanced structure roof and strong underground pressure mining,the layout of the roadway,the selection of the support and the determination of the support control technical parameters,and opened up a new technical approach for coal seam mining under similar conditions.
