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.

Where we began to come really close together again, in the late 60s, and gradually working toward this point, it seems to me, was when Allen began to take a deep interest in Oriental thought and then in Buddhism which added another dimension to our levels of agreement; and later through Allen's influence, Lawrence began to draw toward that; and from another angle, Michael and I after the lapse of some years of contact, found our heads very much in the same place, and it's very curious and interesting now; and Lawrence went off in a very political direction for awhile, which none of us had any objection with, except that wasn't my main focus.

1960年代后期，我们又再次很接近，对我而言，是逐渐走到了一起，艾伦开始对东方思想非常感兴趣，然后是佛教让我们更加紧密；后来因为艾伦的影响，劳伦斯也加入了进来；另一方面，麦克与我失去联系若干年后，再次相逢时，发现原来殊途同归，这现在看来真的很奇怪，也很有意思；劳伦斯后来为政治目的离开了一阵子，我们没人反对，当然这不是我们的关注所在。

The present invention relates to a method for heuristically starting up DC brushless servo electric machine, including the following steps of (1) after powerup of an increment type photoelectric encoder, electrifying a stator winding two by two with identical time interval to generate six-directional stator winding resultant magnetic fields;(2) detecting six different angles rotated by the rotor within identical tiny time interval by the photoelectric encoder;(3) selecting most positive value rotation angle from the six different angles, and determining maximum torque corresponding to the stator winding resultant magnetic field, and implementing servo startup using the maximum torque as constant starting torque;(4) after the zero-point signal of the photoelectric encoder occurring, switching to servo operation with normal constant torsion.

本发明直流无刷伺服电机试探启动方法，采用如下步骤：(1)增量式光电编码器上电后对定子绕组采用相同的时间间隔两两通电，顺序产生六个方向的定子绕组合成磁场；(2)由增量式光电编码器检测出转子在相同的微小时间间隔内分别转过的六个不同的角度；(3)从转子六个不同的角度中选出最大正值的转角，确定相应定子绕组合成磁场对应的最大转矩，并以该最大转矩为恒定启动转矩进行伺服启动；(4)当增量式光电编码器零点信号出现后，切换为正常恒转矩伺服运行。
