矿井地质构造定量评价及其预测

QUANTITATIVE ASSESSMENT AND PREDICTION OF GEOLOGICAL STRUCTURES IN COAL MINE

矿井地质构造预测是人们普遍关注且十分重要的一个长期性课题。本文针对这一难题,从理论到实际介绍了定量评价和预测构造复杂程度的一整套研究方法。首先指出从研究控制矿井构造形迹发生和展布的两个基本条件(即介质条件和应力场条件)得出的主要结论,然后着重讨论了如何确定评价指标及其权重、构造复杂程度及其指标取值范围以及综合评价的方法和结果。在此基础上将全矿井划分出5大类23个块段,得出未采区各块段对应各评价指标的数值,为设计、生产部门提供了可靠依据。

Prediction of geological structures in a coal mine is a very important and long term research project, which is concerned extensively by people. The paper describes a series of methods for quantitative evaluation and prediction of complexity of geological structures. First of all, the main conclusion drawn from the study of two basic conditions, i. e. media and stress field conditions, which controlled the formation and distribution of geological structures in a coal mine,are depicted. The emphasis is laid on how to determine assessment indices, weighing, complexity of structures, range for taking values from indices and the method and conclusions of a comprehensive assessment. On thise basis, the geological structures in the whole mine is divided into five types and 23 blocks. The values of corresponding assessment indices for the virgin area are obtained, which will provide the designing and production departments with reliable criteria.
