B、距离短:一般为几公里至几十公里Short distance: usually several kilometers to dozens of kilometers
C、管径小:一般在100~300mm之间Small diameter: generally between 100 and 300mm
D、压力变化大:开采初期可高达10MPa或更高,开采后期可能降到 1MPa甚至0、 1~0.2MPa 。 Great pressure change: the initial stage of mining can be as high as 10MPa or higher, and the later stage of mining can be reduced to 1MPa or even 0.1~ 0.2MPa.
