摘要
Abstract
The paper makes a force analysis of 11#I steel used in mine as a bridge, calculates the working load, the breaking load, and the maximum bending subsidence value,and obtained the mining maximum bearing weight of the beam, and the density of laying. Through the actual inspection, when crossing the cross roadway and crossing the lower belt to make the bridge, I steel can meet the demand of the underground vehicle load transport.关键词
