结果表明，随着建筑物荷载增大，断层裂隙向下方采空区方向扩展和贯通，造成了浅层地表水向深部采空区渗流汇集。
The results show that with the building loads increase, the propagation of cracks is extending from the top to the bottom of the goaf, and shallow groundwater seeps together into the deep goaf.
增加风速，可以使采空区内高浓度瓦斯向深部推移，从而降低工作面及上隅角瓦斯浓度。
By enhancing the wind speed, the higher concentration methane can move to deeper goaf, which can reduce the methane concentration in working face and top corner.
