| Abstract: | According to the difficulties for gas extraction to sink through No.8 coal seam and easy to priming coal and gas outburst during intake shaft sinking in Guqiao Coal Mine , a method of the deep borehole pre -fracturing blasting was provided to improve the seam permeability , to reduce the time of gas extraction and for the prevention of coal and gas outburst.And the technological process of Deep Borehole Pre -Fracturing Blas-ting was introduced,the application effect was analysed detailedly.It is certified that the application of deep borehole pre-practuring blasting technology to seam opening in mine shaft was effective through practice. |
