| 针对我国煤炭资源储量逐年减少,矿井生产接续紧张的现状.以某矿拟采工作面为例,通过综合分析工作面的地质、水文地质条件,利用突水系数法排除了工作面底板奥灰突水的可能性,确定位于水库下方的F3断层威胁矿井2#煤的安全开采.经计算和分析研究,当采用分层充填开采和预留断层防隔水煤柱宽度为60 m时,可以最大限度地降低矿井开采受水库的威胁,为实现水库下2#煤的安全开采提供理论依据,可以有效缓解矿井生产接续紧张的现状. |
| 英文摘要: |
| In view of the decreasing coal resource, there is not enough coal production to maintain the mine to survive. Based on the analysis of a working face in a coal mine, the paper analyzed the hydrographic and geological conditions and excluded the possibility of ordovician water inrush by using the way of water bursting coefficient. It was determined the F3 fault below the reservoir threatened 2# coal safety mining. After calculation and analysis, if mining hierarchical filling and remaining 60 m coal block was adopted, it could minimize the threat of mining under the reservoir. It provided a theoretical basis to achieve 2# coal safety mining under the reservoir, which could effectively alleviate the tensions of less coal production. |
