在进行水泥矿山设计时,类比拟建和生产矿山的石灰岩抗压强度,可为凿岩、破碎设备选型,爆破参数选择等提供依据。若岩石抗压强度的测定结果偏高,则对矿山设计产生不良影响。本文拟就此进行一些探讨,以期引起注意。就一般情况而言,石灰石抗压强度(公斤/厘米~2)垂直层面为600～1400,平行层面为500～1200。但1979年我院设计马头山石灰石矿时,岩石抗压强度的测定结果(公斤/厘米~2)却为:二层矿垂直层面1459,平
In the design of cement mines, analogical construction and production of limestone rock compressive strength can provide basis for rock drilling, crushing equipment selection, blasting parameter selection and so on. If the measured compressive strength of rock is too high, it will have an adverse effect on the design of the mine. This article intends to conduct some discussion on this in order to attract attention. In general, limestone compressive strength (kg/cm~2) is 600 to 1400 in the vertical plane and 500 to 1200 in the parallel plane. However, when we designed the Matoshan limestone mine in 1979, the measured compressive strength of the rock (kg/cm~2) was: the vertical level of the second-layer mine was 1459.
