Abstract

Abstract

In view of problems of low rate of gas extraction, too many drilling and short period of gas extraction in Linhuan Coal Mine, a method using borehole to implement hydraulic fracturing technology was put forward. The experimental results show that gas standard conditions average scalar was improved 19 times in experimental area of Linhuan Coal Mine, gas extraction cycle was extended more than 3 times, it indicated that the hydraulic fracturing test forms borehole hydraulic fracturing technology applicable to Linhuan Coal Mine. Linhuan Coal Mine is suited to use hydraulic fracturing to realize pressure relief anti-reflection and reducing drilling hole amount.
