Abstract: In order to study each link affected to the mine incline shaft sinking speed in the mine incline shaft sinking period, based on the large cross section shaft as the engineering background, a fish-bone diagram was applied to analyze and restrict the factors of shaft sinking speed. The blasting parameter was firstly optimized and the cut was optimized to be a wedge straight complex cut structure. Thus single cycle footage was increased from 1.9 m to 2.1 m and was increased by 11%. Secondly the support technique was optimized to be a twice support technique. With an application of a full mechanized operation line with a rock drilling rig + crawler loader + flameproof trackless rubber-tyred vehicle, a time consumption of the rock drilling, support and waste rock removing was reduced by 36% in average. Finally,the labor organization was changed from a three eight-hour system to a four six-hour system. The study results showed that with the above measures conducted, a daily footage was reached to 8.5 m in average, a month footage was reached to 240 m and the index was highly increased by 50% and 71% individually. The technical and economic benefits were obvious.
