Rock drivage process for four-arm hydraulic drill rig and breaking-loading-transporting-guniting integrated machine

Abstract

The invention relates to a rock drivage process for a four-arm hydraulic drill rig and a breaking-loading-transporting-guniting integrated machine. The process is mainly characterized by adopting the four-arm hydraulic drill rig to carry out porthole drilling, hole supporting and anchor bolt and cable supporting, and adopting a rock breaking-loading-transporting-guniting integrated machine combining the functions of rock breaking, rock loading, rock transporting and guniting to cooperate to complete rock operation. The process comprises the specific steps of hole drilling, charging, blasting, temporary supporting, supporting, guniting and the like, and the four-arm hydraulic drill rig and the rock breaking-loading-transporting-guniting integrated machine alternately go into a rock driving face area to perform construction operation in the rock drivage process. The process adopts advanced technical equipment, makes the improvement on the existing rock drivage technology, entirely realizes the comprehensive mechanical operation for rock construction, and has the obvious advantages of improving rock drivage footage level, reducing labor intensity of workers, saving human power, raising efficiency, improving field operating environment, reducing the occurence of occupational diseases, effectively ensuring safe production and the like.

Description

technical field [0001] The invention belongs to underground development technology, in particular to a rock roadway excavation technology suitable for comprehensive mechanized development operation of underground rock roadway. Background technique [0002] At present, all kinds of coal mine rock roadway excavation in our country generally adopts gun excavation, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets. The gun excavation is drilled with an air-leg pneumatic drill; manual charging and blasting; the gangue falling from the blasting is manually crushed and then transported out of the working face by a rock rake machine; support. There are mainly the following problems: [0003] 1. The level of mechanized equipment is very low: my country's underground rock roadway mechanized operations have been developed for decades, but most of the processes are still done manually, and the level of mechanized equipment is very low; [0...
