Study on preventing gas outburst experiment by using high-pressure water infused way

Abstract：During excavation coal roadway in serious outburst coal bed, Prevention outburst measure of advanced discharge drilling-hole was selected. Excavation speed was often effected because of gas rapid discharging after firing gas discharge went beyond the limit, and hidden danger was formed.Not only gas and coal outburst were prevented effectly but also gas discharge was well-distributed during excavation roadway after prevention measure of high-pressure water infused way was selected.Working safety was ensured and excavation speed improved.
