| 摘 要： | 为提高炮采面块煤率，提出了松动预裂微差爆破的落煤方案，并对布孔参数和爆破参数进行了调整。工程实例表明，松动预裂微差爆破新技术可以有效减小对顶板的震动和对煤体的破碎，从而提高块煤率。

| Abstract: | To increase lump coal ratio in stopes, a scheme is put forward for coal falling by loose pre-shearing millisecond blasting, and hole arrangement parameters and blasting parameters are adjusted. From some engineering examples, it is seen that this blasting process can reduce effectively roof vibration and coalbody breakage and increase lump coal ratio. |
