利用斯列萨列夫公式评价巷道底板突水危害

Using Slisalif's formulae to evaluate the hazard of floor water invasion

突水是煤矿生产安全的主要灾害之一。随着浅部煤炭资源的枯竭,矿井的深度不断延伸,来自煤层底部奥陶纪灰岩高承压水的危害日趋加剧,针对巷道底板突水严重危害,通过分析突水原因,研究突水因素,以同忻矿二盘区回风巷为例,根据地质及水文地质资料,利用斯列萨列夫公式计算出掘进巷道底板防突水的安全厚度,对底板突水危险性进行评价,提出超前探测的防治水方法,预防底板突水,保证安全生产。

Floor water invasion is one of the main disasters in coal mine production. With the depletion of the shallow coal resources, coal mining becomes more and more deep, and the harm of the high pressure Ordovician limestone water in the coal seam bottom becomes increasingly acute. In view of the serious floor water invasion, through analyzing the water bursting causes and investigating the influence factors, took no. 2 panel return airway of Tongxin mine as example, according to the geological and hydrogeological information, Slisalii＇s formulae was used to calculate the safety floor thickness of avoiding water invasion. The hazard of the floor water invasion was evaluated, and the advanced detection was proposed to protect the floor water invasion, and guarantee the safety production.
