| Abstract: | Based on the gas geology characteristic of the Three-soft and high-gas coal-seam and the gateway rapid driving requirements,outburst prevention technology units have been adopted as follows.The leading gas-release,the leading pressure-relief,the hangerdrill site drainage and water injection of high pressure and so on are united,outburst prediction and effect verification are strengthened.With the group of outburst prevention measures,the magnitude of the initial gas-emission rate(q) is deceased from the maximum of 12 L/min to 2 L/min,the amount of drilling cuttings is deceased from the maximum of 300 Pa to 150 Pa,the driving speed per mensem is up to 80m. |
| Keywords: | three-soft coal seam pressure relief suspension drainage high pressure water injection |
