Study on channel wave reflection method applied to detection of fault

The fault tectonic is one of the important factors affected to the mine mining and heading connection and the mine safety production. In order to ascertai n deposition features of fault and avoid personnel casualty and property loss occurred form fault tectonic exposed without any preparation during the mining and headin g process, No. 2301 coal mining face in Zhaozhuang No. 2 Mine was selected as the experiment site and explorations with the channel wave seismic reflection method were conducted. With the comparison between of exploration and mining results, the paper had a study on the efficiency of method to curate exploration of fault tectoni C. The study results showed that an analysis and calculation were conducted with channel wave velocity of 870 m/s in detection area, a reflecting interface with a south west strike and a extend length about 207 m existed in coal mining face were detected with the channel wave reflection method. The seismic phase was very clear and a fault tectonic was inferred. The exposed mine roadway heading and the coal face mining effectively verified the fault existed, the strike was nearly the same and locati on error was not over 10 m. Therefore, the exploration with the channel wave seismic reflection method could have a good detection effect to the fault tectonic and coul d effectively guide the mine safety production.
