| 中文摘要: |
| 煤层中小断层的出现,会对采掘工作面煤层瓦斯涌出量产生很大的影响,且与小断层的数量有关;基于分析和整理矿山的基础资料,通过量化算法,把小断层数量对采掘工作面瓦斯涌出的影响定量化,并利用最小二乘多项式曲线拟合宏观地分析断层数量对采掘工作面瓦斯涌出的具体影响,发现它对回采和掘进工作面瓦斯涌出的影响总体上大致相同,但局部影响变化有所不同. |
| 英文摘要: |
| The emergence of small faults seams has a huge impact on coal seam gas mining face emission, with small faults related to the number. Based on the analysis and collation of basic data mining through quantization algorithm, the number of small faults is worked out for mining side effects of gas emission quantification. By using the least squares polynomial curve fitting, this paper analyzes the macroscopic number of faults on the specific gas emission mining face. It finds that mining and tunneling face of gas emission impact, on the whole, is roughly the same, but the local impact of the change is different. |
