Abstract:Research purposes: As a causative factor of mountain hazards , the black stratum,distributed in the mountainous area,often gives harm to the engineering and human activities. The study is done on the water - rock interaction mechanism of the black stratum for offering some assistances to the treatment of the mountain hazards and the engineering design.
Research conclusions: The sulfide minerals like pyrite in the black rock can generate sulfuric acid water under water- rock interaction with the oxygen,and it influences the surrounding mineral composition. These actions can lead to the changes of the mineral composition of the black rock and non - black rock nearby to weaken the physical and mechanical properties of the rock materials, resulting in appearance of the mountain hazards under the gravity action. Based on the test and analysis of the black rock and surface water in Dujun area,the failure mode of the black rock slope in the mountain hazards is researched and some engineering control measures are offered.
