Abstract
This paper evaluates a number of techniques for controlling dust and methane during the headgate cutout of retreating longwall sections that use antitropal ventilation (headgate to tailgate). Some of these techniques are effective for both methane and dust control, while others are effective for only one or the other. The techniques include the gob curtain, the walkway curtain, stageloader- crusher control, and the wing curtain. Each improves the health and safety of workers and is economically feasible in hardware cost, setup cost, and maintenance. By combining various of these techniques, mine operators can substantially reduce the dust and methane concentrations at the shearer and ensure the health and safety of longwall workers.
