With the use of drilling data of the working surface, we identified the characteristics of lithology, mineral composition and thickness distribution of fourth aquifer (the "4th aquifer") of loose layer bottom in 7
2
11 working surface of Suntuan coal mine. Based on "Prevention and control of water regulation. Coal mine" and the pumping test analysis, the 7
2
11 working surface "4th aquifer" belongs to weak watery. we can prove and correctly evaluate the watery of loose layer bottom of "4th aquifer" in the working surface, which has an important practical significance on reasonable safe mining coal rock pillar type and increasing the recovery rate of coal resources, fully developing and utilizing coal resources. And it provides a reliable basis for mine to achieve a sustained normal safety production.
