Dust Collector on Longwall Shearer

摘要

The goal of this program is to develop a dust collector system mounted on a ranging drum or arm shearer that will reduce the respirable dust level of the shearer operator by at least 75 percent, be easily and economically mounted on an existing shearer, and will not, through modifications to the shearer, reduce its safety or productive capability. The development program consists of three phases covering the activities of the design of the dust collector system, fabricating and installing it on the ranging arm or drum shearer, and conducting underground field tests on the modified mining machine.
