Abstract: By analyzing ground production and processing and underground fixing of the grid-steel, the main tasks of the fabrication and fixing of grid-steel are achieved. On the basis of analyzing the supporting quota and production quota price constitution of metal support, the additional fixed base price of roadway grid-steel is discussed in detail. According to the principle that same workload is proportional. Comparing the two standard quotas between assembiling reinforcement and metal-net production, it achieves that the the reference fixed base price of roadway additional quota B001 is 4 550 Yuan/t, thus, it provides a reasonable valuation basis for investment estimate budget ( node ) of the grid-steel support in roadway engineering.
