神东天隆集团有限责任公司霍洛湾煤矿22206综采工作面除煤层埋深浅、上覆基岩薄和松散含水层厚等不利条件外,还具有因开采条件限制造成的工作面布置同地表沟谷近上下平行叠加的特殊性。以开采过程中突水溃砂问题为研究对象,通过对矿井水文地质条件、涌(突)水分析的基础上,对煤矿开采过程中突水溃砂灾害发生的可能性进行分析;并结合水资源保护、生态恢复及工程可实施情况,提出“时间+空间、优化接续+防治水工程”的防治水体系,对防治水工程进行了论述。
Shen Dong Tian Long Group Co., Ltd. Hollow Bay Coal Mine 22206 fully mechanized mining face in addition to the shallow depth of the coal bed, the overlying bedrock thin and loose aquifer thickness and other unfavorable conditions, but also due to mining conditions caused by the face of the layout with the surface Valley near the top of the parallel superposition of the particularity. Based on the analysis of mine hydrogeological conditions and surge (sudden) water, the possibility of occurrence of water inrush and sand collapse during the process of coal mining is analyzed, and the water Resource conservation, ecological restoration and project implementation, put forward a “prevention and control water system ” time + space, optimization of connection + prevention and treatment of water projects ", and discussed the prevention and treatment of water projects.
