在系统整理分析陈家岭煤矿2007~2012年全矿涌水量资料的基础上,计算出全矿涌水量的平均值和置信区间,判别出陈家岭煤矿全矿涌水量多年趋势动态和年动态类型均为起伏型,影响总涌水量动态类型的因素有大气降水、地震、水平延伸和观测操作记录不当等。降水量与全矿涌水量的相关系数为0.514,属于正相关、中等相关。汶川地震后总涌水量增加部分来自周边含水层静储量,主要通道为新形成的裂隙、老裂隙的开启和延伸。
After systematically analyzing and analyzing the data of total water inflow from 2007 to 2012 in Chenjialing Mine, the average and confidence intervals of the inflow of the whole mine were calculated, and the multi-year trend and the dynamic type of the whole mine inflow in the Chenjialing Mine were all determined to be undulating The factors influencing the dynamic type of the total water inflow include precipitation, earthquakes, horizontal extension and improper recording of observation operations. The correlation coefficient between precipitation and total mine inflow was 0.514, which was positive correlation and moderate correlation. The increase in total water inflow after the Wenchuan earthquake was due in part to the static storage of the surrounding aquifers. The main channels were newly formed fractures and the opening and extension of old fractures.
