基于组合赋权法的回采巷道快速掘进能力评价及应用

采掘失调是制约当前煤矿高效开采的一大难题.回采巷道快速掘进能力评价能够清晰直观地反映其掘进水平,是保证采掘平衡的关键.基于此论文以四个矿井(A、B、C、D)为研究对象,通过阅读相关文献并结合现场实际情况从"人、机械设备、地质环境、管理"四个方面构建了回采巷道快速掘进能力评价指标体系.基于组合赋权法建立评价模型对四个矿回...

Evaluation and application of fast driving ability of Mining Roadway Based on combination weighting method

Mining imbalance is a big problem that restricts the efficient mining of coal mines. The rapid excavation ability evaluation of mining roadway can reflect its driving level clearly and intuitively, which is the key to ensure the mining balance. Based on this paper, taking four mines (A, B, C, D) as the research object, through reading the relevant literature and combining with the actual situation of the site, the evaluation index system of rapid excavation ability of mining roadway is constructed from four aspects of "people, mechanical equipment, geological environment, management". Based on the combination weighting method, an evaluation model was established to evaluate the rapid driving ability of four mining roadways. The evaluation results show that: the rapid excavation capacity of mining roadway3202in a mine and mining roadway 2301 in D mine basically meets the needs of excavation replacement, while the driving capacity of mining roadway10905 in B mine and mining roadway11602 in C mine needs to be further improved. According to the evaluation results, the key factor that restricts the rapid excavation of coal mining roadway is "geological environment". The research results can lay a solid foundation for the improvement of mining roadway driving level.
