摘　　要：本文通过对贵州省织金县四季春煤矿勘查区工程点可采率、面积可采率、变异系数、稳定程度指数、煤层结构等地质特征的综合分析及研究,针对煤炭资源在地勘时期岩煤层稳定性评价方法的选择及运用,建立了煤层稳定性评价方法的有效模式,为做好煤矿地勘时期的基础地质工作提供了有力保证,就今后煤矿地勘时期岩煤层稳定性评价措施提出了合理建议。Based on the comprehensive analysis and research on the geological features of Sijichun coal mine exploration area in Zhijin County,Guizhou Province,including mining recovery rate,recovery rate per unit area,coefficient of variation,stability index,coal seam structure and other geological features,this paper established an effective mode of coal seam stability evaluation method by the selection and application in geological exploration period.This work provided a strong guarantee for the basic geologic works in exploration period,and made a suggestion for evaluation of coal seam stability during exploration period in future.
