某矿采动顶板矿压显现规律研究

Study on Roof Strata Behavior Laws of A Certain Coal Mine During Mining

摘要: 以某矿首采工作面的工程地质条件为基础,采用现场实测的方法,分析了采区顶板矿压变化情况;结合采场实际情况,建立煤层顶板的工程地质模型,应用数值模拟软件UDEC模拟了采动过程中煤层顶板的矿压显现规律;通过对两者结果进行综合对比分析,得出了采动顶板的来压步距。研究结果为该矿煤层的后续开采、支护提供了参考依据。

Abstract: Taking the engineering geological conditions of the first coal mining face in a certain coal mine as the basis,using field measurement method,the mine pressure changing of mining roof was analyzed.Combined with the actual situation of the stope,engineering geological model of the coal seam roof was set up and the roof strata behavior laws during mining process were simulated by using numerical simulation software UDEC.Through comprehensive comparison and analysis of two sides' results,the weighting step of mining roof was obtained.The conclusion provides a reference for follow-up mining and support of this mine.
