Shielding shield performance under impact loading conditions of free roof collapse
Abstract
The chamber-shield system with the use of mobile shields was proposed for the clearance excavation of thick gentle strata. Production tests of such a system (1959) with the shield LGNK-1 confirmed the high efficiency and serviceability of the mobile shield type.
