摘要
提出了多因子工程地质分析法.以井田为例,对在资源勘探阶段,如何评价开采技术条件,预测煤层顶板和井巷圈岩的稳定性作了分析研究.
In the stage of resourceexploration,the evaluation of mining conditionthe prediction of the stabilities of coal roof,floor,and the surrounding rock in roadwayare the important problems which should be discussed.Based on the consideration of engineering geo-logical factors such as construction of coal fi-eld,characters of bedding and rock groups,va-riable characteristy of lithology,quality gra-dation of rock mass,variable characteristy ofconstruction,the effects discharge river valleyand the analysis of hydrogeologic condition etc,this paper presents and method,named mlti-fa-ctor engineering geological analysis.According to the demonstration of variousengineering geological factors and several ex-amples,the authors evaluate the engineerieg geo-logical stability of coal roof and it is highlyimportant for coal field design,constructionand production.
