Long-hole destress blasting for rockburst control during deep underground coal mining
Original language description
The Lazy Colliery in the Ostrava?Karvina Coalfield of the Upper Silesian Coal Basin adopted modern longwall technology for an underground extraction of coal seam No. 504. This coal seam is located at a cover depth of around 700 m. The seam thickness varied from 3.1 m to 5.0 m in the selected longwall panel. Two overlying coal seams, Nos. 512 and 530 experienced mining at average heights of 58 m and 75 m, respectively, from the planned working horizon of the seam No. 504. The proposed longwall panel wasadversely situated below goaf edges of the workings in these two overlying extracted seams. An analysis of the inter-burden rock mass among these coal seams showed the presence of strong, massive strata of sandstones and conglomerates with uniaxial compressive strength values between 70 MPa and 120 MPa. The stress is measured at different mining stages by Compact Conical-ended Borehole Monitoring (CCBM). A simple laboratory test of the coal sample found a high value of the ratio of the e
