摘要
结合观台煤矿2208工作面的实际数据,对岳城水库下开采厚煤层的安全性进行理论分析。采用相似材料模拟技术,对水体下厚煤层开采时上覆岩层的变形、移动、破坏规律进行模拟和观测研究,特别是对最高导水裂隙带的位置进行观测与分析,进一步论证了在一定的地质条件下进行水体下厚煤层开采的可行性。
Based on the actual data taken from # 2208 coal face in Guantai coal mine, a theoretical analysis is carried out on the safety in the thick coal seam mining under the Yuecheng Reservoir. By using similar material simulation technology, monitoring and analysis are carried out on the deformation, movement and rupture characters of the roof strata when the thick coal seams are being mined under surface water body. A special observation and analysis is given to the location of the highest water leaking fracture zone to demonstrate the feasibility of coal mining in thick coal seams under surface water bodies under given geological conditions.
