..., operators pursued the mining of deeper coal reserves thus coping with increased ground stresses. Sometimes the release of strain energy was not gradual and sudden violent failures of coal occurred. In order to cope with the coal bumps, two basic plans of attack have been historically used: 1) work with the...
