岳城煤矿3号和9号煤层联合开采充水条件分析及防治水技术

Analysis on Water Filling Conditions of Combined Mining Method About No.3 and No.9 Coal Seam in Yuecheng Coal Mine and Its Water Prevention Technology

在对受采掘破坏或影响的含水层富水性、地下水赋存特征、补给、径流条件分析的基础上,采用定量与定性相结合的方法,研究了3号、9号煤层联合开采充水水源、充水因素、充水强度及对矿井安全生产的影响程度,并提出了针对性的防治技术措施。

On the basis of analysis for water aquifer which affected by the mining damage, occurrence characteristics of groundwater, supply and runoff condition, by applying the methods of combining qualitative with quantitative, the authors studied the resource of water filling,the factors of water filling and the intensity of water filling,as well as the influence degree of mining safety for combined mining method about the No. 3 and No. 9 coal seam. The prevention technical measures were also put forward pertinently.
