【摘要】：內(nèi)蒙古巴林左旗小北溝礦區(qū)鉛鋅礦點(diǎn)是2006年由內(nèi)蒙古國(guó)土資源勘查開發(fā)院在1:50000礦調(diào)過(guò)程中檢查AS2-2化探綜合異常時(shí)發(fā)現(xiàn)的。通過(guò)礦點(diǎn)檢查在礦區(qū)地表發(fā)現(xiàn)了多條礦化蝕變帶,其中一條斷續(xù)長(zhǎng)近200m,規(guī)模較大。初步認(rèn)為該區(qū)找礦潛力較大。礦床水文地質(zhì)條件簡(jiǎn)單,礦體頂?shù)装鍑鷰r穩(wěn)固,適于地下硐采。礦床開發(fā)的外部條件優(yōu)越,因此,應(yīng)加大礦床的開發(fā)力度,早日使資源優(yōu)勢(shì)轉(zhuǎn)化為經(jīng)濟(jì)優(yōu)勢(shì)。小北溝礦區(qū)鉛鋅礦圍巖以中酸性——酸性火山巖及其碎屑巖為主,次為變質(zhì)砂巖。礦體嚴(yán)格受北東向壓扭性斷裂構(gòu)造控制。為典型的巖漿熱液礦床。礦床由9個(gè)礦體組成。礦石工業(yè)類型分為三種,分別為:鋅礦石、鉛鋅礦石以及銀鉛鋅礦石,以鋅礦石為主,并伴生有銀、鉛有益組分。采用探槽、平硐及鉆探工程對(duì)礦體進(jìn)行控制,對(duì)具有工業(yè)意義的12條礦體進(jìn)行了資源儲(chǔ)量估算,共獲得資源儲(chǔ)量(332+333)礦石量308.93×104t,金屬量:Pb 5722.28t、Zn 81538.45 t。其中控制的內(nèi)蘊(yùn)經(jīng)濟(jì)資源量(332)礦石量206.76×104t,金屬量:Pb 4519.12t、Zn57595.99t;推斷的內(nèi)蘊(yùn)經(jīng)濟(jì)資源量(333)礦石量102.17×104t,金屬量:Pb1203.16t、Zn 23942.46t、;伴生組分金屬量:Pb 9524.68t、Ag 66610.10kg。并進(jìn)行了礦石可選性試驗(yàn)研究,為礦床開發(fā)利用提供了依據(jù)。通過(guò)對(duì)該礦區(qū)的礦床開發(fā)經(jīng)濟(jì)意義可行性的評(píng)價(jià),小北溝礦區(qū)鉛鋅礦區(qū)現(xiàn)礦產(chǎn)品按現(xiàn)行市場(chǎng)價(jià)格估算,其潛在價(jià)值約合11.33億元人民幣。通過(guò)礦產(chǎn)品的綜合加工回收利用,企業(yè)總利潤(rùn)為3.97億元人民幣,服務(wù)年限為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.
