摘要
为提高芦岭煤矿8煤层地质构造复杂程度综合评价的准确性,在对其定性评价的基础上,遴选了断层密度、断层强度、断层走向影响指数和褶皱平面变形系数4个评价指标,采用灰色模糊综合评价方法对其进行了定量评价,得出了芦岭煤矿8煤层地质构造复杂程度定量评价结果图,划分了构造简单、构造中等、构造复杂和构造极复杂4类构造复杂程度等级。经对比,评价结果与煤矿实际揭露情况基本一致,证明了评价的合理性,为备采区Ⅲ一采区8煤层的采掘提供了科学依据。
In order to improve the accuracy of the evaluation of geological structure complexity of 8th seam in Luling mine, on the basis of the qualitative evaluation, four evaluation indexes were selected, they were fault density, fault strength, fault strike impact index and fold plane deformation coefficient. Then the grey fuzzy comprehensive evaluation method was used to evaluate the geological structure complexity of 8th seam quantitatively. Four types and their distributions of structural complexity were obtained, which were respectively simple, medium, complex and extremely complex. The above evaluation results are basically in accord with mine actual situation, and their validation is reasonable, this provides a scientific basis for mining of the 8th seam.
