摘要：The noise spectrum in a mining chamber is captured by at least one microphone and is digitized and filtered to separate an operation-typical pattern from an operation atypical pattern. The operation atypical pattern is compared with reference patterns to establish the malfunction or vocal command or emergency and the apparatus is automatically operated in response thereto.
