梁宝寺区南部块段下组煤层(16、17 层煤)赋存条件较好,储量丰富,但开发时,存在煤系基底奥陶系石灰岩含水层直接向矿井充水的威胁,制约着下组煤层的充分开发利用。本文在探讨区内奥灰岩溶裂隙发育、埋藏深度基本地质特征的基础上,分析了奥灰岩溶水的赋存特点,指出了奥灰充水的可能性及影响因素,并提出了预防建议。
The lower coal seams (layers 16 and 17) in the southern Liangbosi block have good conditions and abundant reserves. However, there is a threat that the coal-bearing basement Ordovician limestone aquifer will directly fill the mine with water during development, Under the full development and utilization of coal seams. Based on the discussion of the basic limestone karst fissures and the basic geological features of burial depth, this paper analyzes the occurrence characteristics of limestone karst water and points out the possibility and influencing factors of water flooding.
