主井提升系统是煤矿生产的咽喉,是煤炭生产运输的关键环节。目前我国煤矿主斜井大多使用带式输送机,且多为大倾角带式输送机。大倾角带式输送机(倾角大于18°)在设计方面有一定的特点和技术难度。
The main shaft hoisting system is the throat of coal production and is the key link in coal production and transportation. At present, most of China’s coal mine shaft inclined belt conveyor, and mostly for large angle belt conveyor. Large angle belt conveyor (angle greater than 18 °) in the design of certain characteristics and technical difficulties.
