摘要
潘家窑矿的建设,对推进国家能源基地建设、保障国家能源安全具有重要意义。随着我国煤层开采深度不断加大,地质环境条件越来越复杂,煤层底板水害威胁日益凸显。依据潘家窑矿水文地质勘查成果资料,重点研究了潘家窑矿5号煤层断裂构造发育区底板承压水突水危险性评估方法,并结合相关法规标准,运用突水系数法和安全隔水层厚度计算法等多种方法综合进行奥陶系碳酸盐岩裂隙岩溶水带压开采突水危险性评价,对奥陶系碳酸盐岩裂隙岩溶水带压开采的突水危险性进行了综合评价。这些评估结果为制定针对性的承压水突水防范措施提供了重要依据,并为类似水文地质条件下工作面防治水工作积累了丰富的经验。
The construction of Panjiayao Mine is of great significance for promoting the construction of national energy bases and ensuring national energy security.With the increasing depth of coal seam mining in China and the increasingly complex geological environment conditions,the threat of water damage to coal seam roof is becoming increasingly prominent.Based on the hydrogeological exploration results of Panjiayao Mine,we focus on studying the risk assessment method of water inrush from the floor of the fault structure development zone in Panjiayao Mine No.5 coal seam.Combined with relevant regulations and standards,multiple methods such as water inrush coefficient method and safety waterproof layer thickness calculation method are used to comprehensively evaluate the water inrush risk of Ordovician carbonate rock fissure karst water pressure mining,and the water inrush risk of Ordovician carbonate rock fissure karst water pressure mining is comprehensively evaluated.These evaluation results provide important basis for developing targeted measures to prevent water inrush from confined water,and accumulate rich experience for water prevention and control work in working faces under similar hydrogeological conditions.
