Summary:The invention relates to a coal mine tunnel excavation machine, in particular to a large-slope excavation machine with stable operation, which aims to resolve the problems of high risk, waste of timeand increase of workload due to changes of tunnel angles in the blasting operation. The excavation machine can work in large-slope tunnels with the climbing ability of -25-+18 degrees, which changes the former circumstance of adopting blasting in the large-slope tunnels, thereby greatly enhancing work efficiency, reducing the waste of coal resource and guaranteeing the safety of workers. The excavation machine is designed with a reinforced walking part and an improved climbing drive force; a support on the top of a main body and supports on two sides of a rear support enhance the stability ofthe machine during the operation in the large-slope tunnel; the walking part adopts a skid resistant creeper tread and the skid resistant treatment of supporting legs of the rear support, both of which can prevent the machine
