In some cases coal measures, goaf, big caves, and huge faults, as well as high initial stress cannot be avoided in road tunnel excavation. These geological features may make it more difficul practical tunnel construction. So it is necessary to take strong precautious measures against gas outburst, water bursting and roof fall in a tunnel across coal measures with risk of gas outburst. The techniques, such as advance drilling exploration, multiple-cycle shallow depth hole controlled blasting, reinforced supporting, which include concrete grouting and twice supporting, and monitoring measures are often applied in the construction of tunnels and satisfied results are achieved. Results in this paper can help others to get experiences in road tunnel construction with similar geological features.
