摘要
巷道放顶煤法是急倾斜中厚 厚煤层开采技术的一种新方法。该方法的初采钻爆技术是解决顶煤破碎与顺利放出的有效途径之一。介绍了钻爆参数的设计及其在各试验矿井中的应用效果 ,为急倾斜中厚
The method of top coal caving in roadways is a new mining technology used in medium-thickness and high-thickness steep seams. The technique of primary drilling and blasting is an effective way to solve the problem of crushing, caving and transportation. Author introduces the primary drilling and blasting parameters and their applications in many test mines and provides the experience of this new mining method
