Dust control at longwalls with water infusion and foam. Phase II report

Technical Report · Thu May 12 04:00:00 EDT 1983

OSTI ID:6040992

Phase II tasks were: equipment procurement, installation, testing, debugging and modifications for both water infusion and foam spray techniques. These tasks were completed for both Pocahontas No. 3 seam as well as the Upper Freeport Seam. Several modifications were made in the hardware after the initial tests and debugging. Additional hardware has been added to the system to cope with some site specific constraints. Some original hardware was discarded following the initial tests in favor of more efficient equipment or lower cost equipment. Ten important innovations implemented during the contract work are described. Each of these improvements in the systems has been discussed in detail in individual monthly reports. In all the foregoing, the objectives were to simplify the system to make technology transfer to the mine laborers easier, to minimize capital and operating costs of dust control, to avoid interference with coal production operations and to eliminate respirable dust as a health hazard and a bottleneck to productivity on longwalls.
