Abstract
Over 30 tons of coal mine rock specimens were obtained from 13 mines and shipped to various research centers for physical property testing to determine basic criteria and data for feasibility investigations of polymer impregnation of coal mine strata. A portable prototype coring apparatus was designed and assembled to obtain near to in situ condition specimens of coal mine rock samples. Coal mine sites were identified where chemical stabilization of the mine roof strata by polymer impregnation would most likely be feasible and most likely be successful, based on evaluation of the local mining and physical conditions existing at the mine locations.
