what is the proses of quality control in lime stone mines

control in limestone mines can be complex because the entries are fairly wide and have large heights. Rocks falling from a high roof have signiicant injury potential. During a survey of roof stability issues in underground stone mines in the Eastern and Midwestern U.S., Esterhuizen et al. (2007) observed that roof instabilities were
