注浆堵水后试验排水期间矿井残留水量估算

注浆堵水后期,矿井试验排水是对注浆效果进行综合评定,同时也是检查矿井是否具备复矿条件的重要指标。但由于各个矿井地质条件的差异性,致使试验排水得到的一些数据存在一定的歧义,从而误导正常的判断,进而影响矿井生产。以新疆兴陶大北矿业公司大北煤矿试验排水为例,阐述影响矿井试验排水的主要因素,并提出简单估算矿井残留水量的方法,为类似矿井提供了借鉴。

Mine Residual Water Yield Estimation during Testing Water Drainage Duration after Grouting for Water-blocking

In later stage of grouting for water-blocking,the mine testing water drainage is an important index to comprehensive assessment of grouting effect and check if the mine has condition to reopen.But because of differences between mine geological conditions have caused some data from testing water drainage existed certain various interpretations,accordingly can misguide normal judgment,and then impact mine production.Taking a testing water drainage in the Dabei coalmine of the Xinjiang Xingtao Dabei mining industry company as an example has expounded main factors to impact mine testing water drainage,proposed an easy way to estimate mine residual water yield,and provided reference for similar mines.
