INSTRUMENTATION FOR MONITORING LOAD ON

2018-10-11  Geotechnical instrumentation although has been extensively used in the coal mines, still there is no standard procedures for undertaking the investigations as well as type of instrumentation for monitoring the strata behaviour. Over the years, geotechnical instrumentation and strata control technologies have undergone considerable change and it is pertinent that the field engineers must be trained in the state of the art instrumentation for effective implementation of the strata control measures in coal mines. Purpose of the instrumentation should be clear for the planners before commissioning any instruments for understanding strata behaviour. Inadequate number or improper selection of instruments may lead to unsafe decisions by mine planners, while more than required number/type of instruments, not only lead to confusion but also uneconomical. Therefore, experienced strata control engineers with proper understanding of the field problem, and sufficient knowledge on interpretation of the so generated data are primary requirements for a successful instrumentation program. Some of the common requirements for use of the strata monitoring instruments in underground coal mines
