Impact Hazard Assessment of Mine Roadway Excavation Based on FAHP Method
Abstract The evaluation method of the impact hazard during the mining face extraction is relatively mature, but it is difficult to directly apply to the risk analysis of the impact of roadway excavation. Therefore, the fuzzy analytic hierarchy process (FAHP) is introduced into the evaluation of the impact hazard during the excavation of the west belt roadway in second mining area. First of all, geological factors and mining technical conditions are considered to build a hierarchical structure model of impact hazard assessment for coal mining face, and construct the relationship matrix between target layer, standard layer and decision layer. Then, through the fuzzy consistent matrix, the comprehensive influence weight value of impact hazard grade in decision layer is calculated. The results show that the west belt roadway has no impact hazard, which is consistent with the measured results of support loading method and drilling cutting method. The above conclusion indicates that fuzzy analytic hierarchy process (FAHP) can be used to evaluate the impact hazard during roadway excavation.
