The effect of burnt rock on inclined shaft in shallow coal

support of U25 steel arch + shotcrete. By the time of roof fall,12 steel arches were constructed with a spacing of 800 mm,and the thickness of shotcrete is 100 mm,as shown in Figure 3C.When 2# auxiliary inclined shaft was excavated for 380 m,the steel arches near the working face are bent and then the roof falls.Steel-Fiber Shotcrete in MinesConcrete ConstructionThe exceptional physical and mechanical properties of steel-fiber shotcrete make this material valuable in the mining industry.It has proved to offer a safe,low-cost and effective means of providing supplemental support to both roof and ribs; reducing oxygen and moisture attack on rock; constructing stoppings,overcasts and explosion proof bulkheads; and fireproofing timber,urethane foam Steel Sets and Tunnel/Shaft Rings JENNMARImpact-Resistant Arch Sets Impact Resistant Arch Sets are used for immediate roof support.We also manufacture JENNMARs RIP u25 steel arches roof support for mining50- and 100-ton steel props that can be used with JENNMARs lightweight high-strength beam.
