贵州省岩溶山区水文地质条件极为复杂,常规的经验公式对矿井顶板冒落导水裂隙带高度估算结果常常小于矿井实际开采形成的高度,简单、机械地采用常规的经验公式估算矿井顶板冒落导水裂隙带高度并以此确定顶板充水水源的来源,可能导致矿井水防治设计的失误,并影响到了矿井防治水工作。本文以青龙煤矿为例,阐述了该矿矿床水文地质结构特征、勘探阶段估算和矿山开采中实际产生的矿坑顶板冒落导水裂隙带高度差异,分析了造成估算误差的主要原因,提出了岩溶山区矿井顶板冒落裂隙带高度经验公式修正的建议。 |

The hydrogeological condition is complex in the karst mountain area of Guizhou,the mine roof water-conducting crack zone height estimated by conventional formula is usually smaller than the actual height,if the source of roof water is ensured by the conventional formula,the mine water prevention design may has mistakeIn this paper,Qinglong coal mine is taken as the example,the hydrogeological condition,the height difference of estimation in exploration stage and exploitation stage are narrated,the reasons which cause the difference are analysed,then the revised suggestions are given for mine roof water-conducting crack zone height calculation |
