通过对焦化厂硫铵工序的长期跟踪研究，明确了造成硫铵产率波动的主要因素，在焦化流程和配煤比、煤种相对稳定的情况下，对硫铵产率与剩余氨水蒸氨尾气是否进入饱和器、煤气脱硫装置位置、煤气初冷方式、配煤水分、煤气集合温度等因素之间的关系进行了定性分析，得出了以上各种因素对硫铵产率的影响程度的结论，以便科学合理地安排硫铵的生产计划，并为同行业解决硫铵产量波动的问题提供参考。

The paper is based on the theory of inter-function between water and rock, and losing energy in rock mass, brought forward that the water flow has head loss during water flow intruding through the coal seam effective water-resisting layer and energy waste concept for splitting rock mass, and analyzed the form of the remaining water pressure. Through the simulation experiment in the preventing water capability of water-resisting rocks in the coal seam scaleboard, studied the law, character of the losing in water head waste and the relation to pressure, water-resisting of hydrogeology and engineering geology character. Brought forward the new method of calculating the water inrush coefficient.

通过理论分析和实验研究，本文得出以下结论：高承压水在沿煤层底板隔水层导升过程中存在着明显的压力水头损失；同一地层条件下，煤层底板承压水水头压力越大其导升过程中的水头压力损耗就越大；同一水头压力条件下，地层的渗透性越差其阻水能力越强，水流导升过程中的水头压力损耗也越大；在同一介质中，当初始水头压力不同时，水流在导升过程中水头压力的衰减不同，在同一隔水介质中底板含水层水头压力越大其沿隔水层导升过程中的水头损耗也就越大，水头损耗随底板隔水层水头压力增加而呈递增趋势，另外它们相应的水头衰减速率也呈递增趋势，煤层底板隔

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。
