Xingyi City is located at the junction of Guizhou, Yunnan and Guangxi provinces and autonomous region, connecting Yunnan in the west, Guangxi in the south, over 300km away from Guiyang and Kunming and 500km away from Nanning. It is one key city of the Nanning, Guiyang and Kunming Economic Area, the commodity distributing center and the traffic hub. After several years of construction, the modern three-dimensional traffic net with aviation, railway, road and water carriage has been formed in Xingyi City. The convenient traffic makes Xingyi become the key traffic hub southwestward to the sea.

The research results indicate that (1) fault-failure-type water inrush occurs more often than floor-failure-type water inrush under the existence of normal fault;(2) the influence of fault step and dip angle on the feature and position of water inrush is not evident, and water inrush may occur at both coal layer and the floor near working face;(3) the distance of coal column for preventing water inrush should be increased with the increase of fault step and dip angle.

得出以下结论：(1)当存在正断层时，多发生断层破坏型突水，而底板破坏型突水发生的几率较小；(2)突水性质和突水发生位置受断层断距和倾角的影响不大，煤层和采煤工作面附近的底板围岩都可能成为突水涌出点；(3)随着断层断距和倾角的增加，防水煤柱的合理留设距离应随之增大。
