Improved Mine Planning for Limestone Quarry
With a global reputation for superior cement quarry mine planning, RESPEC collaborated with Eagle Materials, Inc. to improve its cement manufacturing facility in Fairborn, Ohio. RESPEC addressed opportunities related to the elemental rock chemistry in their limestone deposit and worked with them to produce a mining sequence to fit their requirements. Our plan optimized the limestone deposit and extended the life of the cement-plant facility. RESPEC identified geologic and chemical characteristics of the limestone rock layers and successfully developed a quality control “blending plan” to mix low-quality and high-quality stone to achieve the client’s stringent quality control targets. The client can now use nearly 20 percent more limestone than previous mining practices.
