【摘要】：内蒙古巴林左旗小北沟矿区铅锌矿点是2006年由内蒙古国土资源勘查开发院在1:50000矿调过程中检查AS2-2化探综合异常时发现的。通过矿点检查在矿区地表发现了多条矿化蚀变带,其中一条断续长近200m,规模较大。初步认为该区找矿潜力较大。矿床水文地质条件简单,矿体顶底板围岩稳固,适于地下硐采。矿床开发的外部条件优越,因此,应加大矿床的开发力度,早日使资源优势转化为经济优势。小北沟矿区铅锌矿围岩以中酸性——酸性火山岩及其碎屑岩为主,次为变质砂岩。矿体严格受北东向压扭性断裂构造控制。为典型的岩浆热液矿床。矿床由9个矿体组成。矿石工业类型分为三种,分别为:锌矿石、铅锌矿石以及银铅锌矿石,以锌矿石为主,并伴生有银、铅有益组分。采用探槽、平硐及钻探工程对矿体进行控制,对具有工业意义的12条矿体进行了资源储量估算,共获得资源储量(332+333)矿石量308.93×104t,金属量:Pb 5722.28t、Zn 81538.45 t。其中控制的内蕴经济资源量(332)矿石量206.76×104t,金属量:Pb 4519.12t、Zn57595.99t;推断的内蕴经济资源量(333)矿石量102.17×104t,金属量:Pb1203.16t、Zn 23942.46t、;伴生组分金属量:Pb 9524.68t、Ag 66610.10kg。并进行了矿石可选性试验研究,为矿床开发利用提供了依据。通过对该矿区的矿床开发经济意义可行性的评价,小北沟矿区铅锌矿区现矿产品按现行市场价格估算,其潜在价值约合11.33亿元人民币。通过矿产品的综合加工回收利用,企业总利润为3.97亿元人民币,服务年限为19年。
[Abstract]:The lead-zinc ore spot in Xiaobigou mining area, Balinzuoqi, Inner Mongolia, was discovered in 2006 when the Inner Mongolia Institute of Land and Resources Exploration and Development checked the comprehensive anomaly of AS2-2 geochemical exploration during the process of 1: 50000 ore survey. Several mineralization alteration zones were found on the surface of the mining area through the ore spot inspection. One of them is about 200m long and large in scale. It is preliminarily considered that this area has great prospecting potential, simple hydrogeological conditions of ore deposit, stable surrounding rock of roof and bottom plate of ore body, suitable for underground cavern mining, and favorable external conditions for ore deposit development, therefore, It is necessary to strengthen the development of the ore deposit and to turn the resource superiority into economic advantage as soon as possible. The main rock mass of the lead-zinc deposit in Xiaobigou mining area is intermediate acid acid volcanic rock and its clastic rock. The ore body is strictly controlled by the NNE compressive and torsional fault structure. It is a typical magmatic hydrothermal deposit. The deposit is composed of 9 orebodies. The ore industrial types are divided into three types: zinc ore, lead-zinc ore and silver lead-zinc ore. Zinc ore is the main ore, accompanied by beneficial components of silver and lead. The ore body is controlled by exploration trough, adit and drilling engineering, and the resource reserves of 12 ore bodies of industrial significance are estimated. A total of 308.93 脳 10 ~ (4) t ore and 81538.45 t ~ (81538.45 t) Zn ~ (81538.45 t) with a total ore quantity of 308.93 脳 10 ~ (4) t ~ (-1) ~ (1) Pb ~ (57) 22 ~ (28) t ~ (10 ~ (3))) of which the controlled internal economic resource quantity is 206.76 脳 10 ~ (4) t, the metal content is 20. 76 脳 10 ~ (4) t, the metal content is 20. 45. 12 ~ (12) t ~ (?) ~ (?) Zn 57595.99 t; the inferred economic resource quantity of ore is 102.17 脳 10 ~ (4) t; 9524.68t Ag-66610.10kg. the ore separability was studied. This paper provides the basis for the exploitation and utilization of the ore deposit. By evaluating the feasibility of the economic significance of the development of the deposit, the present mineral products of the lead and zinc mine in Xiaobigou mining area are estimated according to the current market price. Its potential value is about one billion one hundred and thirty-three million yuan. Through the comprehensive processing and recycling of mineral products, the total profit of the enterprise is 397 million yuan and the service life is 19 years.
