摘要
为保护地表公墓群不受采动破坏,根据观山高岭土矿采矿地质条件,结合条带开采理论提出了5种条带开采方案,采用UDEC3.0数值模拟软件进行模拟计算。计算结果表明:在采高4m,采出宽度25m,矿柱留设宽度10m的条件下,可保证公墓群所处地表变形不超过国家规程规定的Ⅱ级标准并能够最大限度地采出高岭土矿产资源。
Based on Guanshan kaolin mine in situ conditions and combined with strip mining theory, this paper designed five mining schemes in order to protect tombs being destroyed. With UDEC3.0 modeled and calculated, the scheme, 25m mined and 10m remained, can exploit kaolin reserves maximally. What＇s more, the subsidence and distortion of the earth＇s surface in which tombs located didn＇t surpass the second level of the statespecified standard.
