特厚冲积层失水溃砂现场处置及地表沉降监测研究
Hand in scene of water and sands bursting of ultra-thick alluvium and study on the surface subsidence monitoring
摘要
Abstract
In order to solve the surface subsidence because of water and sands bursting of ultra-thick alluvium in Liliangdian coal-mine,sands and water are filled in the shaft peremptorily and the surface subsidence is monitored continuously,which slow down the surface subsidence effectively.Results analysis show that when the gushing water and sand bursting happen to the auxiliary shaft in ultra-thick alluvium,the mine shaft filling and water injection can effectively curb the surface subsidence.The center of subsidence range due to water loss of ultra-thick alluvium is the water point,whose direction is the approximate circle and the maximum subsidence value is 2.7 m.The subsidence area is about 121 853 m2,and the circumference of about 1 455 m.The surface settlement of the water loss does not much effect on the high-speed rail and the high-speed's safety traffic,which is all nearby the mine.关键词
