在对新龙矿业集团公司梁北煤矿的矿井通风阻力测定和自然风压测量的基础上，找出梁北煤矿2007年1月气温突降后所引起的主井风流反向的主要原因，推导出导致风流反向的基本条件，提出在副井至-550 m运输石门之间增加调节设施以增大副井的风阻、增大主要通风机机械风压、在主井下安装压风机人为增大主井的机械风压、减少主井附近热源、对主井的风流进行降温处理和对副井的进风流进行预热以减少主副井之间的风流平均密度差等防止风流反向的控制措施，从而使主井恢复正常的进风状态，消除了矿井安全生产的严重隐患

On this foundation, I develop the automatic control system of the Coal Stacker and supervise and control system with perfect functions ,which may monitor the Coal Stacker work at any time.

According to the theory of coupling of solid and fluid, the influence of fault step and dip angle on the stresses and deformations of coal layer and confining rock along with the pressure of pore water are numerically simulated by finite element method during the process of excavation above a confined aquifer. The mechanism of water inrush and the potential point of water inrush are explored. The distance of coal column for preventing water inrush is also analyzed quantitatively.

根据流固耦合理论，采用有限元数值模拟的方法，针对承压水体上采煤过程中断层参数对煤层、围岩的应力、变形和水压力变化的影响进行了模拟分析，探讨了存在断层时突水的机理和可能的突水点位置，并定量分析了防水煤柱的预留距离。

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。
