Abstract: Abstract: The roadheader is the main equipment of coal mine comprehensive mining in our country, and the scraper conveyor is located behind the roadheader’s loading part, it is a major part for roadheader’s coal transport. As the roadheader technology rapid development, we also encounters many problems about the scraper conveyor with the process of actual using, such as scraper conveyor was jammed, scraper conveyor large gradient transport capacity was declined, scraper conveyor produced dust. In this thesis, through the in-depth analysis about the scraper conveyor, we put forward some improvement measures on the above problems. We hope the thesis could provide some theoretical guidances for the design of roadheader’s scraper convey.
