摘要
鉴于某煤矿60 采区 0420 工作面掘进工程中存在人工效率慢的缺点,同时为了解决掘进难度高和不合理的爆破方式,基于BP神经网络设计,优化爆破参数,建立模型结构,进行现场试验,结果表明:工作面爆破开挖后,巷道成形基本保持完整,少数局部有超挖现象,数值都控制在 100 mm以内,提高了掘进效率,保证了爆破效果.
Abstract
In view of the slow manual efficiency in the excavation project of the 0420 working face in the 60 mining area of a certain coal mine,and in order to solve the high difficulty of excavation and unreasonable blasting methods,based on the design of BP neural network,the blasting parameters were optimized,the model structure was established,and on-site experiments were conducted.The results showed that after the blasting excavation of the working face,the formation of the roadway remained basically intact,with a few local overexcavation phenomena,and the values were controlled within 100 mm,which improved the excavation efficiency and ensured the blasting effect.
