ore block

基本解釋

Through joint venture and cooperation of Shashuya west phosphate rock ore block formed mining enterprises, etc. at the same time.
同時(shí)通過合資、合作等形式新建了宜昌杉樹埡磷礦西礦段等礦山企業(yè)。
By use of the similarity theory, the above parameters are obtained as the basis for the blasting-holes parameter design of ore block by adopting VCR method.
最后根據(jù)相似理論，計(jì)算得到了VCR法大直徑球狀藥包落礦時(shí)的臨界埋深、應(yīng)變能系數(shù)、最佳埋深等爆破參數(shù)，為VCR法試驗(yàn)礦塊孔網(wǎng)參數(shù)設(shè)計(jì)提供了依據(jù)。
On the basis of safety production, selecting appropriate parameters of ore block structure is particularly important for the design and construction of the mine.
在確保安全的基礎(chǔ)上，選取合理的礦塊結(jié)構(gòu)參數(shù)，對(duì)礦山設(shè)計(jì)和建設(shè)尤為重要。
