贵州桐梓三元坝勘查区砂石骨料矿体地质特征及开发利用分析

为评价桐梓县三元坝勘查区建筑用砂石骨料矿石资源及其开发价值，对勘查区建筑用

砂石骨料矿体地质特征进行分析。勘查区内建筑用砂石骨料矿床构造简单，矿体厚度稳定，资源储

量规模大，剥采比低；矿石质量稳定，物理力学性能稳定，矿石主要用途产品质量指标符合混凝土Ⅰ类

粗、细骨料质量指标要求，区内建筑用砂石骨料矿石的开发利用地质条件有利。区内建筑用砂石骨

料矿石开发具有国家及省部委等相关政策扶持，交通便利，市场前景广，适宜开发。

In order to evaluate the ore resources and development value of sand and gravel aggregate

for construction in Sanyuanba exploration area of Tongzi County，the geological characteristics of sand and

gravel aggregate for construction in the exploration area were analyzed. The construction sand aggregate de⁃

posit in the exploration area has simple structure，stable ore body thickness，large resource reserves and low

stripping ratio. The quality of the ore is stable，and the physical and mechanical properties are stable. The

quality index of the main use of the ore meets the requirements of the quality index of the coarse and fine ag⁃

gregate of the concrete type I，and the geological conditions for the development and utilization of the sand

and gravel aggregate ore for construction in the area are favorable. The development of sand and gravel aggre⁃

gate ore for construction in the area has the support of relevant policies of the state，provinces and minis⁃

tries，convenient transportation，broad market prospects，and is suitable for development.
