大阳煤矿矿井地质构造规律研究

Study on the Mine Geological Structure Rules in Dayang Coal Mine

在对大阳煤矿生产时期的构造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,将大阳井田地质构造划分为两个构造区,分析各区小断层发育分布规律,得出"断层平均倾角为60°,断层落差小于5 m的占85%以上,断层分布密度平均为50条/km2"的结论。研究这些分布规律,为该矿合理采掘布置、降低成本、提高储量利用率提供依据。

On the basis of statistical analysis of the structure during the production period in Dayang Coal Mine Geological, structure of Dayang Coal Mine is divided into two tectonic zones combined with 3D seismic data and underground observation data. This paper distribution rules of small fault development in each region, the results showed that average fault dip is 60°, fault throw for less than 5 m is more than 85%, average fault distribution density 50strip/km2. These distribution rules provide the basis for rational mining layout, cost reduction, and raising the utilization ratio of reserves.
