吉林省大栗子外围银多金属矿床开采技术条件

Mining technical conditions of silver polymetallic deposits in the periphery of Dalizi, Jilin Province

吉林省大栗子外围矿床位于吉林省临江市大栗子街道小栗子村管辖。该矿床的地形有利于自然排水。含水层富水性弱,附近无大的地表水体影响。矿床水文地质条件为简单类型。矿体围岩单一,结构面不发育,井巷稳定性好。工程地质条件为简单类型。矿床地处地震稳定的低山地区,无原生环境地质问题,地质环境质量为中等类型。因此开采技术条件定为以环境地质问题为主的中等复杂类型矿床(即Ⅱ-3型)。

The peripheral deposit of Dalizi in Jilin Province is under the jurisdiction of xiaolizi village,Dalizi street,Linjiang City,Jilin Province.The topography of the deposit is conducive to natural drainage.The water yield of the aquifer is weak,and there is no significant impact of surface water nearby.The hydrogeological conditions of the deposit are simple types.The surrounding rock of the ore body is single,the structural plane is not developed,and the shaft and roadway stability is good.The engineering geological conditions are simple types.The deposit is located in a low mountain area with stable earthquake,without primary environmental geological problems,and the geological environment quality is of medium type.Therefore,the mining technical conditions are determined as medium complex type deposits (i.e.type II-3) dominated by environmental geological problems.
