古莲河露天煤矿季节融化层及其剥离

Seasonally Thawed Layer and Its Stripping in Gulian River Open-Work Coal Mine

古莲河矿区霍拉河盆地饱冰季节融化层融化成浆状，影响露天煤矿的春季剥离。采取超前火烧植被和超前剥离植被层措施，使饱冰冻土类型成为少冰冻土类型。利用分条带的剥离方法，可实现季节融化层的超前剥离。

There exist disparities in the seasonally thawed layer influenced by the permafrost in Huola River basin of Gulian River mine area. Slurry in the seasonally thawed layer heavy influences stripping of the Open-Work Mine. In order to strip the seasonally thawed layer ice-rich soil must be turned into ice-poor soil, by means of prior burning or stripping vegetal cover and then stripping with rib. Better stripping effect has been made with this mode.
