Underground coal mine instrumentation and test

A primary objective of this program was to provide a specific operating evaluation of a longwall mining machine vibration response under normal operating conditions. A number of mines were visited and a candidate for test evaluation was selected, based upon management cooperation, machine suitability, and mine conditions.

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

INSTRUMENTATION Mining Science and

Some of the strata mechanics instrumentation that are used can be categorised as follows : Stress Measuring Instruments, It is not possible to directly determine the stress characteristics of rock but it can be evaluated to sufficient accuracy by calculating the stress from other rock properties such as

STRATA CONTROL PROBLEMS OF UNDERGROUND

2011-3-26  With the advent of modern coal mining techniques, it has become imperative to adopt roof bolting as a primary means of support in place of the traditional supports. About 2500 million tons of coal has been locked in pillars of which only about 1000 million tons is amenable to opencast mining, about 1500 million tons is to be extracted by underground mining. Strata control management is one of the major reasons for losing of pillars. Although technology has improved now-a-days with the introduction of Blasting Gallery method, Integrated Caving method and Hydraulic Mining, some of them are unsuccessful with the loss of trials at Churcha, Kottadih, etc., and many more due to lack of suitable strata control techniques. Salient features that lead to typical problems in underground coal mining

Underground coal mine instrumentation and test

The need to evaluate mechanical performance of mine tools and to obtain test performance data from candidate systems dictate that an engineering data recording system be built. Because of the wide range of test parameters which would be evaluated, a general purpose data gathering system was designed and assembled to permit maximum versatility. A primary objective of this program was to provide
