| Abstract: | Open water grouting is one kind of grouting method to stop up water after pour out of water in the tunnel.Based on the practice of open water grouting in Donghuantuo mine of Kailuan Mining Area,the technology and technique of open water grouting are expounded.In the water-rich mine,due to the ratio of electric fees in pumping make up cost of production quite large,and influence on the economic benefit of enterprise,so there is important significance with open water grouting. |
