摘　　要：确定合理的勘查工程间距是矿产资源勘查过程中必不可少的一个步骤,目前常用的勘查工程间距方法主要有验证法、标志值统计法、地质统计学法等。现有方法确定勘查工程间距均或多或少存在一定的缺陷和不足。以云南某铅锌矿为例,按照我国现行勘查规范要求,对现有的勘查工程间距确定方法进行了探讨性完善。认为合理的勘查工程间距应综合考虑现行勘查规范、矿体面积、矿体各类变化系数、置信概率、允许的误差范围等参数后确定,并根据相关参数拟定了勘查工程间距确定公式(规范标志值协调法)。利用该公式可使勘查工程间距更加合理规范,其确定的勘查工程间距与勘查规范综合可确定特定级别资源储量勘查工程间距合理浮动范围,其合理性、适用范围有待进一步完善验证,该公式供读者参考使用。Determining a reasonable spacing between exploration projects is an essential step in the process of mineral resource exploration.Currently,commonly used methods for spacing between exploration projects include validation,indicator value statistics,and geostatistics.The existing methods for determining the spacing of exploration projects have certain defects and shortcomings to some extent.This article takes a lead-zinc mine in Yunnan Province as an example,and explores and improves the existing methods for determining the spacing of exploration projects in accordance with the current exploration standards in China.It is believed that the reasonable spacing of exploration projects should be determined after comprehensive consideration of current exploration regulations,ore body area,various variation coefficients of ore bodies,confidence probability,allowable error range,and other parameters.Based on relevant parameters,a formula for determining the spacing of exploration projects has been formulated(standardized flag value coordination method).The use of this formula can make the determined exploration engineering spacing more reasonable and standardized.The determined exploration engineering spacing,together with the exploration specifications,can determine the reasonable floating range of the exploration engineering spacing for specific levels of resource reserves.Its rationality and applicability need further improvement and verification,and this formula can be used as a reference for readers.
