|
摘要
巷道前方地质构造超前探测是地下工程施工的技术关键和技术难题,利用地震反射波探测技术,采用巷道多次覆盖观测系统采集地震数据,通过能量合成与分解、波场分离、偏移叠加等处理技术,形成矿井地震波超前探测技术(Mine Seismic Prediction即MSP技术),在巷道迎头空间进行全方位的数据采集与处理,可获得巷道探测方向的各种有效的反射波组,该波组与前方的地质界面具有很好的对应性。数值模拟、室内超声波实验与现场探测实验表明,MSP探测技术可以解决巷道前方300m以内的各种地质构造预报。
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.
