Borehole Protection Technology of Screen Pipes for Gas Drainage Boreholes in Soft Coal Seams

Borehole Protection Technology of Screen Pipes for Gas Drainage Boreholes in Soft Coal Seams

In this paper, research was carried out on borehole protection technology using screen pipes, aiming to address the problems of gas drainage borehole collapse and low gas drainage efficiency in soft coal seams, which have low gas permeability and high gas content. An experiment was conducted to stud...
