Abstract: In order to effectively increase gas drainage volume in heading roadway of Shijiazhuang Coal Mine and lower gas concentration in return airflow, according to gas occurrence overview of the mine, it analyzed gas emission sources of heading face, and it used cross-drilled to pre-pump gas in coal roadway strip, then adopted the technology of drilling wall, joint excavation and gas drainage to carry out gas drainage in roadway coal wall. The practice results of 15108 intake airflow roadway showed that the average amount of cross-drilled gas drainage was 1.12 m³/min, it was 1.14 times of parallel drilling, after pre-pumping, the gas content was 7.08 m³/t, which decreased by 9.8% compared to the parallel drilling. It effectively eliminated the risk of coal seam outburst, while finished gas closure during the excavation on both sides of the coal wall, so the maximum gas concentration in return airflow was 0.59%. It was 0.08% lower on average than the bedding drilling program.
