摘　　要：为了充分发挥爆破技术在煤矿开采中的优势,通过调研现有煤矿爆破技术的应用情况,梳理了不同爆破技术适宜的应用领域,可为相关的煤矿从业人员选择适宜的爆破技术提供参考。结果表明:不同硬度岩巷掘进时应用爆破技术可以弥补综掘技术的不足;二氧化碳相变致裂技术可以应用于煤层致裂、卸压,实现煤层增透的目的;在常规及非构造裂隙岩体条件下的露天煤矿开采时,应用爆破技术可以实现很好的爆破与抛掷效果。In order to take advantage of blasting technology in coal mining,through the investigation and research of the application of existing coal mine blasting technology,suitable application fields of different blasting techniques are summarized,which can provide reference for the relevant coal mine practitioners to choose the appropriate blasting technology.The results show that the blasting technology can make up the shortage of the comprehensive excavation technology when excavating in rock roadway with different hardness;liquid CO2 blasting technology can be used to crack and relieve the pressure of coal seam to improve permeability;blasting technology can achieve good blasting and throwing effect under the condition of conventional and non structural fracture rock mass in open-pit coal mine.
