Contract #
200-2011-39886Start Date
9/1/2011End Date
8/31/2016Research Concept
Numerical models for predicting strata instability require reliable, site-specific input data to produce useful results. This research addresses the need for rock mass strength criteria for numerical modeling through field and laboratory testing and by incorporating said criteria into numerical models of several surface and underground mines.Topic Area
Ground Control Overview
Contract Status & Impact
This contract is complete. To receive a copy of the final report, send a request to mining@cdc.gov.
The purpose of capacity-building contracts is to help build the capacity of our nation’s workforce to address critical safety and health problems in U.S. mines by producing graduates with advanced degrees in mining and minerals engineering, and to help develop tenure-track faculty performing research in these areas. Applications for these competitive grants are announced as part of NIOSH OMSHR’s Broad Agency Announcements and are submitted by a Principal Investigator at a U.S. institution offering an ABET-accredited undergraduate degree in mining or minerals engineering.
For further information on capacity-building contracts, please submit a request to OMSHR@cdc.gov.
