FORECAST TO WATER-INVASION DANGER OF THE TENTH COAL FLOOR IN ZHUXIANZHUANG-LULING COAL MINE,ANHUI

We have put forward some new understanding in this paper with a lot of survey and detailed researches on the hydrogeology and structure geology in zhuxianzhuang-luling coal mine at east to Shuxian mining area,Anhui.The microstructure and dynamics have been studied,and the tectonic evolution and sector-division of this region have been advanced.We have also made stetistics of drilling data for more than one hundtend boreholes,and determined tritium istotope and physical property of tenth coal floor,and finished the map of water-invasion coefficient of the whole mining area.Finally,the classified table of water-invasion dangerous degree of tenth coal floor has been obtained,and water-invasion possibility of tenth coal floor has been also forecasted.
