首山一矿己组煤层地质构造复杂程度研究
|
摘要
针对首山一矿己组煤层地质构造复杂程度分级问题,在对矿井地质构造发育特征统计分析的基础上,选取断层强度、断层密度、褶皱复杂程度系数3个评价指标,采用模糊综合评价法对矿井己组煤层地质构造复杂程度进行定量评价,得出了地质构造复杂程度分级图,并对矿井己组煤层按地质构造等级进行分区。评价结果准确反映了矿井地质构造复杂程度,为矿井安全高效生产提供了技术支持。
Based on the grading problem of the geological structure complexity of the F group coal seams in Shoushan No.1 Mine, three evaluation indexes, including fault intensity, fault density and fold complexity coefficient, were selected on the basis of the statistical analysis of the tectonic development characteristics. Fuzzy comprehensive evaluation method was used to evaluate quantitatively the geological structure complexity of the F group coal seams, and the grading map of the geological structure complexity was obtained, and the F group coal seams were divided according to the geological structure grade. The evaluation results accurately reflected the geological structure complexity of the mine and provided technical support for coal mine safe and efficient production.
