在采用无底柱和有底柱分段崩落法的矿山,大多采用扇形中深孔崩矿。目前凿岩设备在定位时,多采用量角器和锤球手工测量定位,在按设计对所凿炮孔进行验收时,也是采用手工测量,二者都费时费事,特别是炮孔位置不准确,影响爆破效果。 In the use of non-pillars and bottomed column caving method of mining, mostly fan-shaped deep-hole collapse mine. At present, drilling equipment in the positioning, the use of protractor and hammer ball manually measure the location, according to the design of the chisel hole for acceptance, but also by hand measurement, both time-consuming and complicated, especially the location of the blast hole is not accurate, the impact Blasting effect.
