中文摘要：
贵州开磷集团用沙坝矿的部分矿体位于金阳公路下面,压矿量达2 262万t。在对矿岩进行了力学参数测试与分析的基础上,选择了房柱式中深孔落矿嗣后胶结充填采矿法,同时利用数值计算方法优选出采场结构参数,实现了公路下磷矿体的安全开采。
英文摘要：
Partial orebody of Yongshaba mine of Guizhou Kailin Group located below Jinyang highway which the amount reaches to 22 620 000 ton.Room and pillar type medium-length hole fall ore afterwards cementation filling mining method based on the test and analysis of mechanics parameters are done on ore-rock.Meanwhile,stope structural parameters are selected by numerical calculation method,and safe exploitation of phosphorite under highway is realized.
