摘要
以兼并重组整合矿井大山沟煤业有限公司为例,通过对下组煤上覆岩层岩性的统计分析,运用经验公式,计算了下组煤开采时的导水裂缝带最大高度,预测了上组煤老空积水对下组煤开采的影响。
Takes the mergers and reorganizations mine of DaShanGou coal Co.,LTD as an example,through the statistical analysis on upper overburden rock lithologic of the lower coal group,by using experience formula,calculates the maximum height of water cracks zone when the lower coal group is exploited.The influence of goaf water of upper coal group on lower coal group mining was forecasted.
