摘要
在对任楼煤矿矿井建设及生产时期的构造资料进行统计分析的基础上,结合三维地震资料及井下观测资料,将任楼井田地质构造划分成5个构造区,分析了各区小断层的发育分布规律,得出其断层平均倾角为64°,断层落差小于2 m的占50%以上,断层分布密度平均为53.1条/km2,基于这些分布规律,可为该矿合理采掘布置、降低成本、提高储量的利用率提供依据。
Based on the statistic analysis on the geological information during the mine construction and mine production period of Renlou Mine, in combination with the 3D seismic information and underground mine survey information, the geological structure of the Renlou Minefield was divided into five structure blocks and the small fault development distribution law of each block was analyzed. The inclina- tion of the fault was 64° in average and the faults with a drop difference less than 2 m were taken over 50% of the faults. The distribution density of the faults was 53. 1 faults per square kilometre in average. Those distribution laws could provide the references to rationally make the mining and excavation layout, to reduce the cost and to improve the utilization rate of the coal reserves.
