| Abstract: | In view of low blasting efficiency and poor quality in tunneling of Longtoushan Gold Mine, the effect of rockmass joints and fissures on tunneling blasting is analyzed. The on-site test results show that some effective measures such as reasonable cutting pattern, blasting parameter improvement, ensured blast-hole quality, etc. can hraise the blasting efficiency and advance per attack, improve the blasting quality and achieve good economic benefit in tunneling in jointed and fissured rockmass. |
