The underground mine manager for the mine must ensure— suitable strata support methods are designed and implemented for the working place; and plans showing the support arrangement in the working place are displayed on noticeboards mentioned in section 178 (1) . The mine must have a standard operating procedure for installing the strata support. A person must not enter the working place unless— the strata support has been installed; or the person is supervising, or engaged in, its installation.
