 The dolomite rock mass at the Yenha domestic waste incineration power plant was studied for its macro and microstructural characteristics. The results showed that the rock mass had a high degree of fracturing, which increased with depth. Additionally, the rock mass exhibited a variety of fracture patterns, including interconnected, unfilled, and angular fractures. Furthermore, the rock mass contained several sets of discontinuities and joints, which were mostly straight and smooth. Finally, the rock mass also displayed a variety of ultramicroscopic fractures, which were folded and located primarily along intercrystalline and crystal interfaces.
