关于煤层稳定性评价方法的探讨

文章以贵州省黔西县金家寨煤矿地质普查工作为例，利用矿区煤层厚度的变化、煤层的可采性、煤层结构等指标，对矿区内可采煤层的稳定性进行了综合性定量评价，并与传统的定性评价方法进行了对比探讨。该方法做到有据可循，改变了目前模糊的定性评价方式，使煤层稳定性的评价更加科学合理，促进煤层稳定性研究工作。

To Discuss Methods To Estimate Stability Of Coal Bed

Taking Jinjiazhai coal mine geological survey work, Qianxi county, Guizhou province as example, the article quantificationally and synthetically estimates the stability of the mining coal bed and compares with the traditional qualitative estimation methods, with the indexes of change of coal bed＇s thickness, coal bed＇s mining＇possibility, and its structure. This methods is based on evidence, and has changed the current intangibly and qualitative estimation. It also makes the estimation of coal bed＇s stability more scientific and accelerates the interrelated study.
