Theory and Technology Application on Rolling Frozen by Straight Holes of Inclined Shaft
LI Wen-tao
Abstract：In Heiliang Coal Mine ,while the auxiliary slope was excavated and lined to the vertical depth 87.2 m or length 223 m ,according to the holes’ data describing of CS19 inspection hole and air shaft inspection hole that the place of vertical depth 113 m or length 289 m is 1.2 m-thick water-bearing coarse sand layer ,and the vertical depth 163 ~ 203 m or length 418 ~ 163 m is water-bearing sandy gravel layer of Neogene.In order to safely and smoothly passing through the aquifer ,working face was temporarily stopped ,and determined to use the construction scheme of straight hole freezing in in‐clined shaft. Through the inclined shaft freezing construction ,achieved the desired effect of capping , sealing bottom ,sealing wall and sealing ends at the same time ,ensure the safety of excavating and lin‐ing construction and continuously constructing.Rolling frozen theory was used in construction ,realized the energy consumption and material saving ,effectively achieved the cost control in the engineering construction.
