Anti-flapping Belt Technology of Belt Conveyor at Grade Change Points in Large Inclination Roadway
Ensuring the smooth and reliable operation of belt conveyor is the basis for realizing the efficient development of underground mining work.Taking DTⅡ belt conveyor in 11305 floor extraction roadway as the research object,combined with the field situation,the operation of the belt conveyor was analyzed,and it was found that the belt conveyor was prone to flapping problems at grade change points.The preliminary design and optimization design of the anti-flapping scheme was carried out according to site requirement.It was proposed to add compression belt wheels at the grade change points and adopt lap transportation to prevent flapping.After analysis,it was found that there were problems such as serious wear and complex structure of the conveyor belt.Therefore,the optimization design was carried out on the basis of the preliminary design.The height and position of the conveyor belt were changed by adding H-frame and reversing drum at the transfer point,so as to meet the needs of the grade change point transportation.The optimization design was analyzed in detail.After engineering application,the DTⅡ belt conveyor in 11305 floor extraction roadway run smoothly,and the conveyor belt at the grade change points did not appear flapping,deviation,scattering,abnormal wear and other problems,and the application effect was obvious.
