露天煤矿爆破高效经济综合评价及优化路径研究

Study on efficient and economical comprehensive evaluation and optimization path of open-pit coal mine blasting

露天煤矿常使用爆破开采煤炭,爆破作业的爆破效果对后续的开采环节和最终的经济效益有很大的影响。为了有效地评估东露天矿的爆破效果,提高该矿的爆破质量和经济效益,使目前的爆破方案达到最优,使用模糊数学与层次分析法,综合评价了该矿的爆破效果,找出爆破工作中的薄弱环节。通过建立BP神经网络预测优化模型,对现有爆破参数取得的爆破效果进行了预测,检验了预测效果的合理性,为爆破设计参数的确定提供了更科学有效的方法。

Open-pit coal mines often use blasting to mine coal,the blasting effect of blasting operations has a significant impact on the subsequent mining process and the ultimate economic benefits.In order to effectively evaluate the blasting effect of the East Open-pit Mine,improve the blasting quality and economic benefits of the mine,and optimize the current blasting scheme,fuzzy mathematics and analytic hierarchy process were used to comprehensively evaluate the blasting effect of the mine and find out the weak links in the blasting work.By establishing a BP neural network prediction optimization model,the blasting effects of existing parameters are predicted,and the rationality of the prediction effect is verified,which provides a more scientific and effective way to determine the design parameters.
