摘　　要：地面钻探与三维地震成果显示山东某矿103_(下)03工作面东侧发育1条最大落差近300m的边界断层,利用YTZ3(B)型自记式地震仪在103_(下)03工作面运输巷开展非在线式随掘地震与钻爆法超前探测断层的对比试验,非在线式随掘地震解释断层上盘与设计切眼最近距离110m,断层面较平直,走向约62°;钻爆法超前解释断层上盘与设计切眼最近距离108 m,断层面较平直,走向约61°。试验结果显示:非在线式随掘地震、钻爆法超前探测与地面钻探与三维地震综合解释的断层边界基本一致,3种独立的探测方法互相印证,提高了断层边界位置的探测精度,也表明了非在线式随掘地震探测巷道前方断层的有效性。Surface drilling and 3D seismic results show that a boundary fault with a maximum drop of nearly 300 m is developed on the east side of the 103 lower 03 working face of a mine in Shandong Province.YTZ3(B)type self-recording seismometer was used to carry out the comparison test of non-on-line seismic while excavating and borehole-blasting method for advanced fault detection in the transportation roadway of 103 lower 03 working face.The non-on-line seismic interpretation showed that the nearest distance between the fault hanging wall and the designed cutting eye was 110 m,the fault plane was relatively straight and the strike was about 62°.The drilling and blasting method is advanced to explain that the nearest distance between the fault hanging wall and the designed cutting eye is 108 m,the fault plane is relatively straight and the strike is about 61°.The test results show that the fault boundaries of non-on-line seismic while excavating and borehole-blasting method are basically consistent with the comprehensive interpretation of ground drilling and 3D seismic.The three independent detection methods verify each other,which improves the detection accuracy of the fault boundary location,and also shows the effectiveness of non-on-line seismic while excavating to detect the fault in front of the roadway.
