Investigation of a method for monitoring stress changes in the burst prone seams of southwestern Virginia
A review of coal bumps. their nature. causes.
prediction. prevention. and mitigation is presented. The
design and construction of a borehole stressmeter is
discussed. Laboratory testing. which yielded promising
results of the stressmeter (inclusion) is presented
along with preliminary field test results. Laboratory
testing involved comparison with the results of a
two-dimensional finite element model of the physical
laboratory test with those of the physical test itself.
Results correlated well. The results of the field test
indicate the need for further research into the practical
application of the solid inclusion method in the field.
