文档介绍：四川省巴塘县夏塞银铅锌多金属矿床详查设计
——以①号矿体北段为例
摘要
在野外地质调查基础上,结合矿区普查地质资料,依据夏塞矿床①号主矿体的矿体规模、主要矿体形态及内部结构、矿床构造影响程度、主矿体厚度稳定程度和有用组分分布均匀程度等地质特征,最终确定夏塞矿床为第Ⅱ类勘查类型,勘探间距为100×50m。在此基础上,结合矿区南段地质工程资料,选取矿区北段进行详查设计,简单如下:
(1)①号矿体北段垂直矿体走向布设勘探线,方向为65º,间距为100m,在南段探矿工程基础上,往北依次编号为P2、P4……P22、P24。
(2)在勘探线布设基础上,编绘了夏塞矿区①号矿体北段勘探工程设计平面图,;12条探槽,总长约1200m,1440m3,槽探样240个;钻孔24个,钻探总长度约3600m,钻探样360个。并选取P2、P14、P20三条勘探线剖面作为代表设计了探矿钻孔。
(3)参考《地质调查项目预算标准(2010年试用)》,,对设计的勘探工程经费进行简要的预算,。

Thorough examination on the northern section of No.① Orebody of the Xiasai silver, lead and zinc polymetallic deposit, in Batang County, Sichuan Province
ABSTRACT
Based on geological survey in the field, together with the geological data of mining census, according to the geographical features of the No.① main orebody of Xiasai deposit, including its scale, shape, inner structure, intensity of influence, degree of stability in thickness and ponents evenness etc, Xiase deposit is ultimately determined as the second type for perambulation. Its exploration space is 100 × 50m. On this basis, referring to the data of the southern section of mining geology engineering, we select the northern section for thorough examination and design, briefly as follows:
(1)Lay prospecting lines in No.① orebody northern section perpendicular to strike of the orebody with the direction of
