Design of Bulkhead for Controlling Water in Underground Mines.
MISSING :36 pages
This Bureau of Mines report presents three methods for designing bulkheads to impound water underground: (1) thin and thick plate design; (2) South African plug design; and (3) single and double bulkhead seal design. Related areas critical to the long-term effectiveness of underground water impoundments are also addressed. These include bulkhead anchorage, concrete specifications and placement, the grouting of permeable strata, and the sizing of barrier pillars. A case study involving hydrostatic tests conducted on a single bulkhead seal constructed in the safety research coal mine of the Bureau's Pittsburgh Research Center is presented in an appendix.
