Practical measure research of large sections auxiliary roadway controlling

With the development of comprehensive mechanized mining,the transportation system of large section workings are necessary.In order to match the Mugua mine's high strength mining,it makes the roadway extremely difficult to maintain under the circumstance of thick top-coal and large cross-section.The influence of mine safety and efficiency production is serious.The practical measure research of large sections roadway controlling,the research includes: the bolt support design of auxiliary roadway in Mugua mine;the monitoring of surrounding rock deformation and supporting force,the monitoring data analysis of mine pressure;The result indicated that the supporting design of auxiliary roadway is reasonable,the surrounding rock is stable.The practical measure research will bring great economic and social benefits for the coal mining,and it has high application value.
