摘要
岩巷的爆破质量对煤矿安全生产具有重大影响。为了实现对岩巷掘进爆破施工效果的定量评价,从技术经济、安全施工、围岩保护三个角度出发,利用AHP法确定各级指标体系的权重,然后结合实际巷道爆破情况,通过采集多位专家的定量打分数据,建立影响因素综合评价矩阵,计算得出岩巷爆破质量的综合得分,直观说明其施工质量水平。研究结果表明,评价结果与实际情况基本一致,综合评价模型具有较好的可靠性。
The blasting quality of mine rock roadway has great influence on safety in production of coal mines.In order to achieve the quantitative evaluation of mine rock roadway blasting effect,this paper from three perspective,technical and economic,safety and quality of construction and protection of surrounding rock,using the analytic hierarchy process to determine the weight of the index system at all levels,and then combining with the actual rock roadway blasting,through collecting rating data given by a number of experts,establishes a comprehensive evaluation matrix with the factors affecting the quality,then calculates comprehensive score of blasting quality in mine rock roadway.It shows the construction technology level directly.The research result shows that the evaluation result is basically consistent with the actual situation,and the comprehensive evaluation model has good reliability.
