伏岩煤业抽采负压沿钻孔深度变化规律

Changing Laws of Drainage Negative Pressure Along With the Change of Drilling Depth in Fuyan Coal Industry

  • 摘要: 为研究抽采负压沿钻孔深度的变化规律,将不同孔深(0、20、40、60、80、100 m)的抽采负压作为考察指标,在伏岩煤业进行测定研究。结果表明:抽采负压沿孔深变化规律符合指数函数p=ae-bL形式,当孔口负压为13.00~46.13 kPa时,百米抽采钻孔负压沿程损失为1.896~3.382 kPa,平均2.468 kPa。
    Abstract: In order to study of drainage negative pressure change along with the change of drilling depth,it took drainage negative in different drilling depths(0 m,20 m,40 m,60 m,80 m and 100 m)as the investigation index,and carried out in Fuyan Coal Mine. The test results showed that the change laws of negative pressure change along with the change of drilling depth is accorded with the exponential decline law p=ae-bL,the loss of negative pressure per 100 meters was 1.896 to 3.382 kPa and the average is 2.468 kPa,when orifice negative pressure was 13.00 to 46.13 kPa.
