朱庄煤矿Ⅲ63采区6煤开采安全性研究

Research on Mining Safety of 6 Coal Seam in Ⅲ63 Mining Area of Zhuzhuang Coal Mine

以朱庄煤矿Ⅲ63采区6煤层开采为例,通过对矿井水文地质资料进行系统分析,确定影响煤层开采的主要控制因素;应用层次分析法对各主控因素的权重进行计算;利用Mapgis软件绘制各主控因素专题图,并对专题图进行复合;建立底板突水预测模型,对6煤层开采过程中太灰含水层突水危险性进行预测。

Take the mining of 6 coal seam in the Ⅲ 63 mining area of Zhuzhuang coal mine for example, through the systematical analysis of the hydrogeological data of mining area, determining the main controlling factors that influenced the mining of coal seam; The weight of the main controlling factors was calculated by Analytic Hierarchy Process; Mapgis was used to draw the thematic layers of main controlling factors ,then composite these layers; The water inrush prediction model was built to forecast the water inrush dan^er from the Taivuan limo,~t^n~ nn th,~ ,~.~,~l,,;t^t;,...,f ~ ~1
