Abstract: Taking the construction basalt ore in a certain area as the research object, this paper systematically explores and analyzes the mineral composition, chemical composition, physical and mechanical properties as well as industrial processing technical performance of the ore. Combined with the geological conditions of the deposit, resource reserves, mining technical conditions and regional market demand, it comprehensively evaluates the development and utilization value and prospect. The research results show that the saturated compressive strength of basalt in this area ranges from 80.27 MPa to 152.77 MPa, the crushing value is 13%, the soundness is 1%, there is no alkali-aggregate reactivity hazard, and the radioactivity index meets the relevant standards, complying with the Class Ⅰ-Ⅱ criteria for construction stone materials. The ore is suitable for the standard process of three-stage crushing combined with shaping and screening. The total proven resource volume is 44.623 million tons with a stripping-to-ore ratio of 0.17∶1 and simple mining conditions. It can not only serve as a stable supply base of high-quality infrastructure aggregate, but also extend to high value-added fields such as basalt fiber, which is of great significance for supporting the construction of regional infrastructure and the high-quality development of building materials industry.
