The test site of the IESCS was 470 m from the stop mining line. The roof lithology above the coal seam was mudstone (0.7 m) and fine sandstone (12.8 m). The roof had good stability with low crack development. The direct bottom was sandy mudstone, which swelled and softened slightly after exposure to water. Download : Download high-res image (165KB)
