煤矿地质构造评价指标系统的建立与优选

Establishment and Optimization of Comprehensive Evaluation Indicator System for Geological Structure of Coal Mine

本文以褶皱、断层构造较为发育的砚石台煤矿为例,通过勘探与开采揭露地质资料的系统分析,以及矿井地质构造发育规律、形成机理的深入研究,首次建立了一整套评价煤矿地质构造复杂程度的指标体系。旨在对井田已采区的煤层构造复杂程度进行定量综合评价,并对未采区地质构造发育程度进行量化预测,从而指导煤矿安全与高效采掘。最后,采用灰色关联分析和逐步回归分析法相结合,实现了全部评价指标的智能化优选。研究成果所获得的优选指标可直接服务于地质构造综合评价数学模型及其配套软件系统。

raking Yanshitai colliery in Chongqing .city as an example, which the strata am intensely folded and faulted, by way of systematic analysis of exploration and mining data, as well as intensive study of geologic strueture laws and its formation mechanism. The objectives of this paper are to establish a wholly set of index system for comprehensive evaluation and forecast of geological structure, evaluate quantitatively structural complexity of unmined - out area, as well as to forecast quantitatively structural development degree of un non - mining areas. By which the high and stable coal output will be realized safely. Finally, these indicators have been optimized and selected by means of grey relation analysis and stepwise regression analysis program. These optimal index can directly serve in the mathematical evaluation model of geologic structure and its software system.
