根据1977年8月冶金工业部重新修订后颁发的《冶金矿山爆破和炸药生产安全暂行规程》笫65条,露天爆破时人员与爆破地点的安全距离(R),不小于下列的规定(表一)。本文结合表1所列适用于平坦地段爆破的R值推导一个简明的公式,计算出不同爆破方法和山坡地形时的最小安全距离,并把计算结果列成表,以利在实际工作时应用。 According to Article 65 of the Interim Provisions on the Safety of Blasting and Explosive Production in Metallurgical Mines released after the revising of the Ministry of Metallurgical Industry in August 1977, the safety distance (R) between the site and the site of blasting during opencasting is not to be less than the following (Table 1 ). In this paper, a concise formula is deduced from the R values ​​listed in Table 1, which are applicable to the blasting in a flat section. The minimum safety distances for different blasting methods and hillside topography are calculated, and the calculation results are tabulated to facilitate the practical application.
