Abstract
The preserved area of snail fossils, with layers of up to 10 m deep, in the lignite coal mining area of Mae Moh in northern Thailand has been set aside; however, there is concern about the impact of weathering and erosion in the long term due to the breakage and low strength of snail fossils. Therefore, the present study aims to investigate the strength properties of the snail fossils in association with the effect of particle breakage using a direct simple shear test. Disturbed snail fossil samples were collected from the subsurface of the Mae Moh coal mine outside the preservation area. The results indicate that snail fossils are highly compressible due to the angular and delicate snail particles. In addition, the internal friction angle of snail fossils is close to 31°, which is much lower than that of other carbonate sands, but comparable to those of hard particle sands or commonly encountered sands.
