主 题：Coal mining Longwall shields Dust control
摘 要：A laboratory apparatus (shield dust simulator) was designed and constructed to simulate the dust generated during the advance of longwall hydraulic roof supports,or *** objective of the study was to develop a tool that could be used to test the hypothesis that foam applied to a mine roof prior to a shield advance could be used to reduce the respirable dust generated during shield *** paper will outline the design parameters for the development of thesystem,as well as describe baseline testing of coal and limestone *** show that the average instantaneous respirable dust concentrated during simulated shield *** intervals were calculated from the instantaneous respirable dust data to determine the repeatability of the data produced by the device.
