Influencing Factors Analysis of Drilling Efficiency of Coal Mine Gas Control

Mine gas disaster is becoming increasingly serious,and drilling work plays a very important role in gas control.How to reduce the drilling influencing factors and improve the efficiency of drilling continually,to ensure the balance of mine pumping,digging,mining and achieve the safe and efficient mining is important part of study.For the current drilling status,the influencing factors identified through systematic analysis provide reference for underground gas control and drilling work.
