赵庄二号井东盘区目前采用综采放顶煤开采,进入西盘区后煤层平均厚度减小,且起伏变化波动明显,选择合适的厚煤层采煤方法成为赵庄二号井亟待解决的关键问题。对一次采全高综采采煤法和综采放顶煤采煤方法 2个方案进行比较,根据矿井实际情况确定影响采煤方法的关键因素,并运用9标度层次分析法对4个准则层因素与12个子准则层因素进行权数分配,结合专家独立打分获得的评判集完成采煤方法的模糊综合评判,评判结果表明,赵庄二号井西盘区适合采用综合机械化放顶煤开采。
Zhaozhuang No.2 well east panel currently adopts fully mechanized top caving mining. After entering the west plate area, the average thickness of the coal seam is reduced and the variation of the undulation is obvious. Choosing suitable thick seam mining method to become Zhaozhuang No.2 well needs urgent solution The key issue. Comparing two schemes of one full-height fully mechanized coal mining method and fully mechanized top coal caving mining method, the key factors affecting coal mining method are determined according to the actual conditions of the mine, and the 9 criterion levels Factors and 12 sub-criteria factors, and combined with the judging set obtained by experts scoring independently to complete the fuzzy comprehensive evaluation of coal mining methods. The results of the judgment show that it is suitable to adopt mechanized caving coal mining in the west of Zhaozhuang No.2 well.
