|
摘要
以岱庄生建煤矿3上煤层开采为例,综合运用数值模拟、经验公式预计以及现场实测3种方法来确定其导水裂缝带发育高度,并对比分析其优缺点,以此提高结果的准确度。结果表明:3种方法对应的结果分别为60,43.6和44.7m,而前两种方法具有其局限性,因此综合确定了31302工作面3上煤层开采顶板导水裂缝带高度为44.7m。
It taking upper coal seam mining of 3# coal seam in Daizhuang Shengjian coal mine as example,water flowing fractured zone height was confirmed by the following three method,numerical simulation,empirical formula and field measurement,and then the accuracy rating of results was improved according contrastive analysis of it' s merits and demerits. The results showed that the results of the three methods were 60 m,43. 6 m and 44. 7 m,respectively,the former two method had it' s limitations,so water flowing fractured zone height of upper coal seam mining in 31302 working face was confirmed as 44. 7 m.
