Technical Field
[0001] The utility model relates to the technical field of coal mine fully mechanized mining equipment, and more specifically, to a narrow multifunctional anchor digging machine. Background Art
[0002] After years of mining, the problem of unbalanced excavation and support in tunneling has become increasingly prominent. To solve this problem, a mining and anchoring machine integrating excavation and anchoring functions has been introduced to effectively improve the efficiency of anchoring. With the increase of mining depth, the pressure of the mine has increased significantly. Under the action of mine pressure, the return tunnels of the coal mining face are generally deformed and bottom bulged. The deformation of the tunnel is serious and reaches 2-3m, which seriously affects the efficiency of coal mining and the safety of personnel and equipment. The existing tunnel repair methods are mainly manual repair with pneumatic picks and mechanized repair with tunnel repair machines. The first manual method is not the current development trend of repair operations due to its low efficiency and poor personnel safety. The second mechanized repair method generally uses a tunnel repair machine for bottom cleaning and side brushing operations. Due to the limitations of the machine body size and tunnel space, it is only used in the return air tunnel, that is, there are certain operational limitations. At the same time, the function of the tunnel repair machine is relatively single, and it can only perform bottom cleaning and side brushing operations on the non-belt conveyor side (the chute without a belt conveyor), and cannot perform side brushing on the inner side of the belt conveyor (the chute with a belt conveyor) and anchor support. At present, most (80%) coal mines in my country organize a large amount of manpower and equipment to carry out repair operations such as brushing and bottom cleaning on deformed tunnels to ensure the needs of coal mining. However, the efficiency and safety of tunnel repair operations are low, which has become a bottleneck problem restricting the high production and efficiency of coal mines.
[0003] As the mainstream equipment in underground coal mine tunnels, anchor diggers are widely recognized for their integrated mechanization of tunneling and anchoring functions, which alleviates the problem of digging and supporting balance, improves anchoring efficiency, and reduces labor intensity. Although they have similar repair functions as tunnel brushing machines and tunnel repair machines, the current anchor diggers are large in size and poorly adaptable to narrow tunnels. They cannot be withdrawn to the chute where belt conveyors and other equipment are set to replace tunnel brushing machines and tunnel repair machines for operation, resulting in high equipment costs for forming tunnels and great limitations.
