Type of Report: Excerpt: OSM Fill Shear Strength Project

Abstract:

Shear box was designed and fabricated (Phase I/RD No. 94). Test fixture will

provide data for OSM to establish regulations on shear strength parameter of

land fill material. Field conditions were simulated (Bureau of Mines mine roof

simulator). Vertical load representing overburden and horizontal load producing

shear was applied to fill material of various mixtures and conditions.

Sandstone from Amherst Strip Mine No. 3 in Lundale WV was received for testing

under Phase 2 of RD No. 4. Fill material was used to perform 3 dry shear tests

of 100% durable fill. Presently, OSM fill shear strength program is on hold

pending funding.
