区域性赤峪断层落差及延展方向分析

Analysis of Regional Chiyu Fault Throw and Extension Direction

为深入研究赤峪断层在紫晟煤业的落差及延展方向,减少构造损失煤量。通过地表踏勘查看断层出露情况,井下钻探探测断层延展位置,补充施工地质勘探钻孔对比岩层缺失层位,判明了区域性赤峪断层在紫晟煤业东南部呈现为4条密集分布的断层组,断层组在2-107工作面外围约115m,断层破碎带宽约220m,总落差190~325m,由西南至东北部总落差逐步减小。

In order to further research the Chiyu fault in Zisheng coal throw and extension direction.Reduce the amount of coal lost in structure.The outcrop position of the fault can be observed by surface reconnaissance.Underground drilling detects the location of fault extension.Comprehensive analysis of strata deletion in geological exploration drilling. Revealed the regional Chiyu fault presents four densely distributed fault groups in the southeast of Zisheng coal mine.The Chiyu fault group is about 115 m outside the 2-107 working face.The fault fracture zone bandwidth is about 220 m.The total fault throw is190 to 325 m.The total fault throw decreases gradually from southwest to northeast.
