| Abstract: |
| The deviation of separated source prediction method is larger when it is applied in the fully mechanized coal face. Because it does not distinguish the differences of different aspects of work. Based on the separated source prediction method principle, the paper divided the gas source into five parts, and according to the laws of gas emission the calculation formulas are been putted forward. And then the separated sources prediction method and improving formulas are been used to predict the gas emission value of the 13180 coal mining face. And the result was then been compared with the measured values in the process of production. Proving that the improved formulas are more accurate and it can be as a common means. |
