玻璃钢是一种新型工程材料，用其制造煤矿管道供井下给排水及通风使用时，支撑跨度决定于管材的强度及管道允许的最大挠度。在使用中尽量不出现反坡，以防冷凝水的聚积。本文在确定支撑间距的设计中，同时采用了强度和刚度条 件，在研究设计中，合理地控制铺设间距，为节省材料和施工投资提供了理论根据。 FRP is a new type of engineering materials, with its manufacture of coal mine pipe for underground water supply and drainage and ventilation, the support span depends on the strength of the pipe and the pipe allows the maximum deflection. In the use of try not to appear anti-slope, to prevent the accumulation of condensed water. In the design of determining the supporting distance, the paper adopts the conditions of strength and stiffness at the same time. In the research design, the reasonable control of laying distance provides theoretical basis for saving material and construction investment.
