Description

Continuous gangue throwing and filling equipment and method for coal mine tunnel Technical Field The invention relates to the technical field of filling equipment, in particular to continuous gangue throwing and filling equipment and method for a coal mine roadway. Background With the current development of mine exploitation equipment to large-scale and mechanical, various resources are being exploited continuously from underground. Especially, a large amount of gangue generated during underground coal mining of a coal mine is required to be lifted and transported to the ground through the underground and then transported to a designated stacking area, and a 'gangue dump' is formed in daily accumulation and moon. The stacking mode not only occupies a large amount of land resources, but also often causes accidents such as spontaneous combustion, landslide and the like, so that serious environmental damage is caused, and tens of components such as S, P, C and the like contained in the gangue cause pollution to the atmosphere, water sources, soil and the like at different degrees, so that the living environment of human beings is seriously influenced. The gangue underground filling is a novel solution for the treatment and utilization of the gangue. By filling the coal gangue into the pit, not only limited coal resources can be replaced and ground subsidence can be reduced, but also the occupied land of gangue can be saved, and the pollution of dust, solid particles, harmful gas and spontaneous combustion heating to the surrounding environment can be eliminated, thereby realizing the comprehensive treatment of the coal gangue. Currently, the underground gangue filling equipment mainly comprises a gangue throwing device and a belt. Along with continuous filling of the gangue, the gangue conveying device needs to continuously move backwards at a smaller step distance, and meanwhile, the length of a conveying belt needs to be frequently adjusted, so that auxiliary procedures are more. If the operation is missed or the protective measures are not in place, the safety accident is easily caused, and the production efficiency is extremely low. In addition, the highest projection position of the filling operation in one step is basically fixed, the whole filling process is intermittent movement, so that the top of the gangue pile body is wavy and cannot be fully supported, the filling rate is low, and meanwhile, the filling operation requirement of a larger roadway section is difficult to meet due to structural limitation. In the prior art, 201810942021.3, a continuously filled gangue casting system, 201822236590.4, a mining gangue casting machine, 202321066130.6 and underground gangue casting complete equipment disclose a scheme of a basic split type filling device of a gangue casting device and a conveying belt, but the filling needs small steps of intermittent backward movement, the length of the belt is frequently adjusted, auxiliary procedures are multiple, the safety risk is high, the production efficiency is low, the casting position in a single step is fixed, the gangue is piled up in a wave shape, the top cannot be fully divided, the filling rate is low, the structure is limited, and the filling operation of a large-section roadway cannot be adapted.
