Intrduces a equipment of low seam mining support-ZY3300/07/13D the low seam hydraulic support.
介绍了一种薄煤层采煤支护设备—ZY3300/07/13D薄煤层液压支架。
The results showed that the higher of the mining influence coefficient, the longer the time interval between the up seam mining and the low seam mining would be favorable to the up seam mining.
结果表明，采动影响系数越大、上下煤层开采间隔的时间越长，对上部煤层的开采就越有利。
