| Summary |
"This paper does not pretend to originality; it is an attempt to bring to light the causes and the mechanism of rockbursts, as exposed in the literature. Furthermore, an endeavor has been made to give a comprehensive picture of the prediction, prevention, and control methods of rockbursts. Briefly, what has been done in the field of rockbursts, and what remains open to investigation is submitted to the reader. The choice of rockbursts as a thesis subject appears to be justified by the geologic interest of the question. Detailed geologic observations, and particularly the recording of all the structural features which may be present in a given mining district, are required before any attempt can be made to solve the rockburst problem in that district. Furthermore, an economic interest is attached to rockbursts; due to the fact that in deep mines, the control of rock pressure constitutes a problem which may be more or less serious than control of temperature and which will have a definite economic influence in the cost of mining. At the present time, the miens critically affected by rockbursts are scattered all over the world, and are relatively few. However, should the present trend towards deeper and deeper mines be continued in the future, the economic influence of rockbursts and associated ground movements could become increasingly important"--Introduction, leaf 4. |
