Embodiment Construction
[0037] When the excavating and anchoring integrated machine is working, it performs parallel operations of excavation, temporary support, network laying, steel belt laying, and bolt support. It is suitable for excavation, temporary support and anchor net support of rectangular coal roadway. The overall dimensions of the model are about 11m in length, 3.8m in height and 5m in width, and are suitable for large-section coal roadway excavation. The specific height and width of the roadway can be met through equipment design and manufacture.
[0038] The excavation work described. The cutting mechanism adopts two horizontal drum structures with telescopic sections, the diameter of the drum is 1000mm, and the length is the same as the width of the roadway. The lower cutting drum (6) is the main cutting mechanism, which is fixed by the fixed structure frame (8), and can move up and down around the fixed rotating shaft to expand the cutting range and connect with the upper cutting d...

The invention relates to a parallel operation method for tunneling, temporary support, connection net laying, steel strip laying and anchor bolt support in the tunneling process of a coal roadway of acoal mine and a tunneling, supporting and anchoring integrated machine, and belonging to the field of coal mine coal roadway tunneling complete equipment and technical methods. The tunneling, supporting and anchoring integrated machine is characterized by being composed of a tunneling and supporting truck, an anchor bolt locomotive and a scraper conveyor; and devices required by coal roadway tunneling cutting, temporary support, connection net laying and steel strip laying are all arranged on the tunneling and supporting truck. According to the roof-cut temporary support parallel operation method, full-length cutting horizontal rollers are adopted, the lower cutting roller protrudes forwards to cut a roof coal roof, the upper cutting roller does not move up and down in the post cutting process, and temporary support is carried out on a newly exposed roof in real time; and all anchor bolt (cable) drilling machines required for roadway anchoring are arranged on the frame type anchor bolt locomotive in sections. The method comprises the steps that in the operation cycle initial state, connection net laying and steel strip laying operation should be completed; firstly, the tunneling and supporting truck advances to execute cutting and temporary support operation, and simultaneously, the anchor bolt locomotive executes anchor bolt support operation in situ; secondly, after the tunneling and supporting truck advances by a preset distance, connection net laying and steel strip laying operation is executed; and finally, the anchor bolt locomotive follows to advance to merge with the tunneling and supporting truck.
Description
technical field [0001] The patent of the present invention relates to a method for parallel operation of excavation, temporary support, network laying, steel belt laying, and bolt support in coal mine roadway excavation, and a method for realizing the parallel operation of an integrated machine for excavating and anchoring. The utility model belongs to the field of complete sets of equipment and technical methods for tunneling in coal mines and roadways. Background technique [0002] Under the background of unbalanced coal mine excavation, the complete set of equipment and technical methods for coal roadway rapid excavation have made great progress in China in the past 10 years. However, the effectiveness of parallel operation of excavation, temporary support, laying network and laying steel strips, and bolt support, as well as the problems of large number of equipment, scattered layout, poor linkage performance and narrow space for material transportation in the roadway hav...
