摘要
开采保护层是防止煤与瓦斯突出最经济、最有效的技术措施,对不具备开采条件的极薄非突出煤层,用钻机式采煤机开采后,能够对近距离被保护煤层起到消突作用,并实现工作面无人作业,确保人员安全,同时也为极薄煤层的资源回收提供了途径。
The mining protector is prevents the coal and the gas prominent most economical,the most effective technical measure,to does not have the mining condition side thin non-prominent coal bed,after drilling machine type coal mining machine mining,can protect to the short distance the coal bed to play disappears suddenly role,and realizes the working surface nobody work,guarantees the personal security,simultaneously has also provided the way for the extremely thin coal bed resources recycling.
