EXPERIMENT AND APPLICATION STUDY OF FORE DETECTING BY MSP METHOD FOR GEOLOGICAL STRUCTURE IN LANEWAY

The fore detection and forecasting for geological structure in laneway are very difficult to be solved in underground engineering construction.Therefore,we attain Mine Seismic Protection technology(MSP)by utilizing reflection wave theory.The technology gets seismic data by multifold in laneway and processes these data through some processing technique including synthesizing and decompounding,wave field separation and migration stack etc.All kinds of geological interfaces of reflecting waves in fore laneway can be gained by collecting and processing the data from laneway section.Some numerical simulation test and ultrasonic wave experiment and practical detecting application indicate that MSP technology can detect many geological structures within 300 meters in the fore of laneway.
