提出用分段空场法开采缓倾斜矿体时，可以采用侧向爆破抛掷出矿技术来提高矿石的回采率。通过理论研究和技术设计说明了使缓倾斜矿体的下盘小倾角范围矿石向上盘方向抛掷到积矿堑沟的依据，并以现场实际回采爆破参数和矿房尺寸为条件，用数值计算的方法进行了论证。

It is suggested to apply the lateral pin-point blasting technique to improve the extraction ratio in shallow slope mining by sublevel open stoping.The fact that the ore in the small inclination section of shallow slope bottom wall is slung to ore accumulation trench along top wall is explained through theoretical research and technical design,which is verified by numerical simulation based on the practical blasting parameters and room size.
