Those rarely refer to the researches about water pressure function mechanism. In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

实际上，煤层底板高承压含水层水沿隔水底板岩层向上导升过程中，存在一定的沿程水头损失和劈裂岩体裂隙的能量损耗，下伏含水层高压水在底板隔水层下部劈裂导升一定的高度后，在导升段的能量消耗很大，这时作用于有效隔水层段下部的实际水压已远远小于含水层中的观测水压，真正作用在有效隔水层上的水压为残余水压P_c，对底板有效隔水层起破坏作用的有效水压力亦应为残余水压。

With the increase of lasting time of retaining water by the1st sub dam, some phenomena will occur, such as water infiltrates into the dam body gradually, the phreatic surface rises constantly, the unsaturated region reduces corresponsively, the pore water pressure increases and the shear strength decreases continuously in the site which is influenced by water infiltration.

The average diameter decreases monotonically with increasing effective confining pressure,which is defined as the difference between confining pressure and pore water pressure.

试样的平均直径随着有效围压的增长而单调减小。在此，有效围压被定义为围压和孔隙水压之差。

From the water pressure test and the collapsing examples, the thesis analysis the force expression of Karst collapse in water table dropping down, and presents that the additional stress from water table descending in overlying soil layer and rock, which is equal to approximately the descending depth of water table, which can be applied to about ten meters descending depth.

针对地下水位波动引发的岩溶塌陷进行了专门性研究。通过试验文章指出了岩溶区地下水位受迫下降至基岩面以下时的力学效应为：附加力在一定范围内，与在基岩面以上一样，等于水位下降的幅度值，并与盖层下基岩中洞穴的形态及体积无关。

Therefore, by comparing particle distribution of the spraying under different water pressure, and the nozzle's outlet velocity simulation get by Ansys, which is a software for mechanical simulation, a proposal of the application of 1.5mm nozzle, 8Mpa water pressure on the spot was put forward.

在比较多种光学测粒仪的基础上，选择Winner313系统测量不同孔径喷嘴在不同供水压力下喷雾雾场的粒径分布。通过分析比较喷嘴在不同压力下喷雾雾场的粒径分布和Ansys模拟得到的喷嘴内部及出水口速度场，建议现场应用1.5mm喷嘴、供水压力为8MPa进行喷雾。
