Micro-seismic Laws in Influence Range of Tunneling Roadway with -1 200 m Buried Depth

Roadway excavation will cause maldistribution of stress surrounding rock, which will affect the micro-seismic activity in the workface or roadway. Studying the scope of influence area is in favour of revealing the relationship between underground roadways and workface, and strengthening the prevention and treatment of rock burst disaster. This paper is from the view of earthquake information of the SOS micro-seismic monitoring system in Poland to analyze seismic distribution law of heading face and tunneling through fault in transport roadway with 1 200 m buried depth, and the influence law of tunneling on the turning area of track lane, based on this, the leading influence range of roadway excavation is summarized.
