Description

The purpose of this acquisition is to obtain the specialized laboratory equipment necessary to support PMRD’s ongoing rock‑mechanics and ground‑control research by ensuring the consistent preparation and testing of geological specimens aligned with rock preparations and testing standards. This includes acquiring a complete rock‑specimen cutting system capable of producing accurate, repeatable cuts on rock, coal, concrete, asphalt, and core samples; a computerized grinding machine that will significantly reduce specimen preparation labor while supporting major research projects such as seismic potential forecasting and panel‑well optimization; a creep test apparatus to provide essential time‑dependent rock‑property data for numerical modeling in coal and stone mines; and a triaxial testing machine required to determine cohesion and friction angle parameters for specimens collected from mine sites. Together, these systems will improve specimen quality, enhance laboratory efficiency, reduce the costs and delays associated with external testing, and provide high‑quality mechanical data needed to support advanced modeling, pillar‑design evaluations, roof‑stability assessments, and the development of comprehensive databases for U.S. coal and stone mines. All equipment will be delivered to the Pittsburgh Mining Research Division facility within the established period of performance, ensuring PMRD has the necessary capabilities to meet current and future research demands.
