Construction method for advanced water exploration and drainage in underground coal mine
The invention discloses a coal mine underground advanced water exploration and drainage construction method which comprises the following steps: S1, confirming a coal mine well digging range, and determining a sample point; s2, geological layer exploration is carried out on the sampling points; s3, obtaining a water detection line position and a warning line position of the sample point according to the data of the geological layer of the sample point; s4, firstly draining water and then digging a well; s5, the hoistway is safely supported; according to the method, the sampling points are obtained at equal intervals, then the geological stratums of the sampling points are surveyed, and data of the geological stratums of the sampling points are obtained, so that water exploration and drainage with different depth requirements are carried out in each interval area of a coal mine well, and advanced water exploration and drainage in which water drainage is carried out before well digging are achieved; the problem that when an existing coal mine well is dug, a well way is prone to collapse due to high-pressure water seepage of a geological layer is solved, and normal digging of the coal mine well and life safety of workers are guaranteed.
本发明公开了一种煤矿井下超前探放水的施工方法，所述方法包括以下步骤：S1、确认煤矿井掘井范围，确定样点；S2、对样点进行地质层勘测；S3、依据样点地质层的数据，获得样点的探水线位置和警戒线位置；S4、先放水后掘井；S5、对井道进行安全支护；本发明通过先等距间隔获取样点，在对样点的地质层进行勘测，已获得每个样点地质层的数据，从而实现对煤矿井每个间隔区域内进行不同深度需求的探放水，从而达到先放水在掘井的超前探放水，解决现有煤矿井掘井时井道容易受地质层的高压水渗水出现塌陷的问题，保证了煤矿井的正常掘井和工人的生命安全。
