| 中文摘要: |
| 贵州北部的务—正—道地区是贵州省近年来新发现的又一重要铝土矿成矿区,预计总资源量可达×亿吨。笔者等以本成矿区矿床(矿体)的特殊性,结合现有矿产勘查规范和矿政管理要求,对该地区铝土矿勘查技术问题的认识与处理进行总结。认为:大型矿床(或大矿区)应允许两种勘查类型并存；矿床勘查类型的确定应在普查工作结束之后或详查阶段之初；333资源量工程间距应与矿床变化程度相适应,变化小的则稀,变化大的则密；在(121b)块段内出现无矿天窗,由见矿工程向无矿工程外推的块段划为122b较为恰当；边界指标的确定,应通过测算后作出合理的选择。勘查深度以定在平坑坑口标高之下100~200 m为宜;在详查阶段应允许提交少量(334)？资源量。 |
| 英文摘要: |
| The Wu-Zheng-Dao bauxite deposit area, located in the north of Guizhou province, is a newly discovered bauxite metallogentic area, the predicated resource tonnage of bauxite ore can reach several hundred million tons. Based on the metallogenetic characteristics of the bauxite deposit (orebody) in this region, in combination with the requirements of the current mineral exploration regulations and the administrative management of mineral resources, the authors proposed the following points as for the bauxite deposit exploration and development: two classes of exploration approaches should be applied for the large-sized bauxite deposit (or mine) ; the deposit exploration type should be determined after the end of the general exploration stage, or before the beginning of the detailed exploration stage; The exploration grid used for the resource estimation of the Class 333 should be compatible with the spatial variation of the deposit, i.e., if the deposit has small variation, then the exploration spacing can be made as wide, and dense spacing if the deposit varies in the space; the block reserve surrounding the 121b Class Reserve should be defined as 122b Class Reserve from the current exploration drilling area in those blocks where the opening exists; the selection of the cut-off grade of the deposit should depend on the reasonable estimatation of the economical parameters; the exploration depth has better defined as 100m to 200m below the current adit level; in the detailed exploration stage, a certain amount of 334 Class Resource tonnage should be allowed to outline and submit. |
