Mining Technology of Fast Passing Thick and Hard Rock during Fully Mechanized Driving

当综采工作面揭露坚硬夹石层,在进行客观分析之后,提出了在头尾巷深孔爆破结合工作面密集型浅孔爆破相结合的方法,大大地提高了生产效率。

When uncovering the thick and hard rock on the fully mechanized working face, how to select the mining technique？ Through objective analysis, the paper presents a combined method of head-tail roadway deep-hole blasting and working face intensive shallow-hole blasting. The method improves the productivity greatly and is worth spreading.
