Characteristics of Pressure Relief Gas Extraction in the Protected Layer by Surface Drilling in Huainan by Xiaozhang Tong, Hu Wen, Xiaojiao Cheng, Shixing Fan, Chunhui Ye, Mingyang Liu, Hu Wang

“…To study the behavior of gas extraction from the protected layer by surface drilling, the common characteristics of gas extraction concentration and gas extraction quantity are summarized through the collection of key parameters of surface drilling and a combination of data and figures, with the background of 11−2 coal protection 13−1 coal in the Huainan mining area. The research results show that the flow of pressure relief gas extraction of the protected layer by surface drilling has three stages: a rising period, stable period, and decay period. …”
