Abstract:

China lacks construction experiences with common methods in inclined mine shaft of thick gravel layer. Combined with construction practices of the first inclined mines of Cailiao and Huifeng in Yili coal mine, the supporting programme is designed and quite a few supporting trials have been studied due to abundant water and non-aqueous sites. According to the field test results, the deformation of trestle gets larger and it is more difficulty to support in the abundant water site; The temporary support of beam joined with reinforced concrete is an effective method to support the large section inclined shaft in non-aqueous gravel layer. The deformation and the pressure grow rapidly while the shaft is in the abundant water gravel; it is proved that forepoling supporting together with the temporary support and reinforced concrete can control the surrounding’s deformation and keep its stability. It is inferred by site test results that significant errors might occur when it is applied to calculating the pressure of gravel layer surrounding by Terzaghi and Coulomb earth pressure theory.

Key words: gravel layer, inclined mine shaft, supporting, field tests
