| Abstract: | On condition that the available equipment is unsatisfed,a method tooptimize hydraulic jet parameters is obtained in th large diameter well in coal mine. It'ssuitable for the pump with low pressure. The details are introduced in the paper.And thefiels practices are very successful in gaining economic and social profits. The method willbe an important guide to the coal mining company geological and metallurgical agency tooptimize the hydraulic jet parameters. |
