基于组合赋权法的回采巷道快速掘进能力评价及应用

Evaluation and application of fast driving ability of mining roadway based on combination weighting method

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采巷道快速掘进能力进行评价。评价结果为:A矿3202回采巷道、D矿2301回采巷道快速掘进能力基本满足采掘接替需要,B矿10905回采巷道、C矿11602回采巷道掘进能力有待进一步提高。并依据评价结果确定了制约煤矿回采巷道快速掘进的关键因素为"地质环境"。

Mining-excavating 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 miningexcavating balance.Taking four mines(A,B,C,D) as the research object,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 is established to evaluate the rapid driving ability of four mining roadways.The evaluation results show that:the rapid excavation capacity of mining roadway 3202 in A mine and mining roadway 2301 in D mine basically meets the needs of mining-excavation replacement,while the driving capacity of mining roadway10905 in B mine and mining roadway11602 in C mine needs to be improved.According to the evaluation results,the key factor that restricts the rapid excavation of coal mining roadway is"geological environment".
