| Abstract: | Based on the specific condition of the Schoenberg's theory of linear slippage in fractured media and the wave field numerical simulative conclusion of cracked coal beds,the ratio between the velocity of the P-wave and that of the P-SV converted wave in three-dimensional three-component(3D3C) seismic exploration is calculated, and the gas and water in the cracked coal bed of Qianjiaying Coal Mine is researched and predicted. The prediction result is proved by mining practice. The 3D3C seismic exploration technology provides an effective means for comprehensive treatment of gas and water in coal mines. |
