ABSTRACT:
The method and apparatus for mapping mine excavation or tunnel entry conditions by mounting an array of sensors on a vehicle some of which provide knowledge of the vehicle location in the entry and others of which provide knowledge of entry conditions and by interpreting data collected from the sensors, a map can be generated of the entry strata for a given vehicle location in the entry. This map can be compared with similarly generated maps to indicate changes in the entry condition.
