摘　　要：针对输煤系统落煤管堵塞、落煤筒腐蚀磨损漏粉、胶带运行跑偏、撒煤,输煤栈桥粉尘浓度超标,噪音大等问题,提出将传统落煤管改造为防堵抑尘曲线落煤筒,改造后,彻底解决了落煤管堵塞、落煤点不正、胶带运行跑偏等问题,使粉尘浓度降低到6 mg/m3以下,噪音降低到80 dB,输煤系统堵煤漏煤情况得到改善,现场工作环境得到改善。Point at the problems of coal drop pipe blockage, coal cylinder corrosive wear powder leakage, belt running deviation, scattered coal in the coal conveying system, coal dust concentration exceed the standard and big noise, reconstructed the coal drop pipe for the transformation with the anti-block dust suppression curve of coal chute, completely solved the falling block, belt running deviation. The dust concentration was reduced to 6 mg/m^3 below, the noise is reduced to 80 dB, blocking coal and coal leakage situation, and the site working conditions were improved.
