摘要
岩石在完全松散和挤压状态下的碎胀系数能够为掏槽爆破、挤压爆破中补偿空间的计算提供重要依据。取金山店铁矿的粉矿和块矿设计试验,分别测定其在完全松散和挤压状态下的碎胀系数,为金山店铁矿爆破补偿空间的研究提供重要科学依据。
Under the condition of totally loose and squeezing, the coefficient of bulk increase can provide a pivotal evidence for calculating compensating space in cutting blasting and tight blasting. Based on the specimen of powder ore and block ore, the coefficients of bulk increase at the condition of fully loose and squeezing are tested, which provides an important and scientific guidance for blast compensating space.
