Theory and Practice of Gas Drainage in Fully mechanized Caving Working Face of Very Soft Inflammable and Very Thick Outburst Coal Seam |
| |
| Abstract: | The unbalance abnormal gas burst with fully mechanized caving method in very soft inflammable and very thick outburst coal seam is main technical puzzle. The knowledge of 'weighing and redoubling' as well as the practice of using roof road for gas drainage successfully control and limit the gas overflow at the upper corner of fully mechanized caving working face and in return way and roof road. |
