摘　　要：合理的生产勘探网度能够准确地控制矿体产状、形态、规模、构造等特征,准确的、稳定的矿体形态对采掘工程设计、采矿方法的选择、矿石质量控制均具有一定地质指导依据。本文主要通过选取矿石体积、品位、矿石量变化百分率、矿体水平面积重合率、矿体水平形态歪曲率5个指标来对比分析不同阶段下的矿体变化情况,总结出合适的生产勘探网度。Reasonable production and exploration network degree can accurately control the occurrence,shape,scale,structure and other characteristics of ore body,the accurate and stable shape of ore body has certain geological guidance basis for the design of excavation engineering,the selection of mining methods and the control of ore quality.This paper compares and analyzes the change of orebody in different stages by selecting five indexes:volume,grade,percentage of change of orebody amount,coincidence rate of orebody horizontal area and distortion rate of orebody horizontal form,the suitable network degree of production and exploration is summarized.

关 键 词：生产勘探 矿体面积重合率 矿体形态歪曲率
