A kind of fast excavation material and shotcrete conveying method of turning rock roadway

Abstract

Provided is a turning-rock-roadway rapid excavation material and a conveying method of whitewashing material. A turning belt conveyer is adopted to convey materials, and the following basic measures and additional measures are adopted at a roadway turning section to solve the turning problem of the belt conveyer: (1) the turning radius of a belt is enlarged; (2) a carrier roller at the turning is provided with a mounting support angle; and (3) a grooving angle is increased. The additional measures comprise the steps that (1) a longitudinal beam suitable for a turning curvature radius is machined, namely the length of the inner side longitudinal beam is shortened, so that the belt conveyer has conditions of forming the turning radius; (2) an H frame is machined, wherein the outer leg of the H frame is slightly high, and the inner side longitudinal beam is shortened to enable the belt to incline inwards slightly, so that the belt conveyer has the conditions to form the turning radius; and (3) the level of tightness of the belt is adjusted, so that the turning belt is slightly loose compared with the tension degree of a linear running belt, and overlarge stress of the inner side of the belt is avoided. A bottom belt of the belt conveyer is adopted to convey the whitewashing material to solve the problem of whitewashing in the construction of an air return way and a track hidden inclined shaft, a whitewashing machine base is located on the rear side of the belt conveyer tail, and the bottom belt is used to convey the whitewashing material to the whitewashing machine in the whitewashing process.

Description

technical field [0001] The invention relates to a solution to the problem of belt transportation of small-angle turning roadway in rock roadway excavation and the problem of rock roadway grout transportation, which can improve the working efficiency of rock roadway. Background technique [0002] Coal is the foundation of my country's national economic and social development. It has always occupied a relatively high proportion in my country's primary energy production and consumption structure. For a long period of time in the future, coal will still be one of my country's main energy sources. The current fast-growing economy has put forward higher requirements for the development of the coal mining industry. [0003] Rock roadway excavation is the vanguard of mine excavation operations, and its excavation speed and efficiency have a great influence on the normal excavation succession of mines. For a long period of time, rock roadway excavation has maintained the operation m...
