MSHA rules on underground proximity detection systems adopt several NMA recomendations

first_imgAmerica’s National Mining Association (NMA) is examining a final rule issued recently by the Mine Safety and Health Administration (MSHA) requiring new proximity detection technology to be installed on all continuous mining machines used in underground coal mines. The rule is effective beginning March 15 with staggered deadlines varying with the manufactured dates of machines in use. The final rule accepts NMA’s suggestion to replace MSHA’s proposed requirement for fixed distance detection zones around continuous miners with a performance standard for determining when machines would automatically be stopped. As finalised, the rule also addresses a second NMA concern by allowing more time for re-built machines to implement the requirements for installing the proximity technology.NMA will comment further on the rule after consulting with member companies and soliciting their views of its impact on operations.last_img
