在煤层中注入水或含各种物质的水溶液,对预防煤矿中各种有害现象(产生煤尘、矿山冲击地压、煤和瓦斯突出,内因火灾,等等)的有效性,取决于选择合理的参数——初始(最大)注水压力P;注水速度v;水的耗量q;钻孔的注水量V;钻孔长度L;封孔深度lr;孔间距B及注水时间T.这些参数的数值互有联系和影响,同时与诸如地质和采矿技术因素以及水泵的性能也有关.彼尔木斯基煤炭科学研究所于1964～1965年在基捷洛夫斯基煤田对上述问题作了研究.由于煤层注水的参数与许多因素有关,所以用数学统计法来确定这些参数的最合理数值是最恰当的.在有充分的大量的实验资
The effectiveness of injecting water or aqueous solutions containing various substances in the coal seam to prevent various harmful phenomena in coal mines (coal dust generation, rockburst, coal and gas bursts, internal fires, etc.) depends on the choice of reasonable Of the parameters - the initial (maximum) water injection pressure P; water injection speed v; water consumption q; drilling water injection volume V; drilling length L; sealing depth lr; hole spacing B and water injection time T. These parameters The values are interrelated and influential, but are also related to technical factors such as geology and mining technology, as well as the performance of the water pump. The Institute of Petrochemicals of Murskinsky conducted a study on the above problems in the Kijlovskyi coalfield from 1964 to 1965 Since the parameters of coal seam water injection are related to many factors, it is most appropriate to use mathematical statistics to determine the most reasonable values for these parameters.When there is sufficient experimental capital
