根据苏联采矿技术安全规程的规定:‘炮眼若使用点火爆破时,在准备坑道和大竖井以及在倾斜角30°以上的斜坑内,一个爆破工点炮的次数不得超过8次;在水平坑道和在倾斜角30°以下的斜坑及采矿坑道内,则不得超过16次’。该规程又规定‘若一个爆破工的点炮次数超过上述规定的次数时,必须将各组炮眼的导火线紮成一束,而使用点火筒点炮’。由此可见,苏联对於矿山爆破作业安全是如何重视,如何严格。可是目前我们矿山的爆破作业规程,还未达到这样的水平。爆破工既未能履行上述规定的点炮次数,而矿山对於使用点火筒点炮也并未加以利用。现在我们各矿的爆破工都是直接站在掌子头上点燃很多的甚至超过上述规定的点炮次数,这是不安全的非常危险的操作。我们必须消除或减少爆破工直接在掌子上
According to the Soviet Mining Safety Regulations: ’When blasting is used with blastholes, the number of blasting blasting points must not exceed 8 times during the preparation of tunnels and shafts, and in slant pit angles of over 30 °; in horizontal tunnels and No more than 16 times in inclined pits and mining tunnels with an inclination of 30 ° or less. The rules also stipulate that “If the number of shots fired by a blasting worker exceeds the number specified above, the firing lines of the blasting guns of each group must be bundled and the firearm fired.” Thus, the Soviet Union for mine blasting operations how to attach importance to safety, how strict. However, blasting operations at our current mine procedures, have not yet reached such a level. Blasting workers failed to fulfill the above requirements of the number of shots, and mines for the use of fire-point gun has not been used. At the moment, blasting workers in all our mines are directly ignited on the head of a large number of cannonballs even exceeding the above requirements. This is a very dangerous and unsafe operation. We must eliminate or reduce the blasting workers directly on the palm
