Simulation experiment research on reducing span effect with the anchorage cable

With the development of science and technology and enhancement of productivity in our country,more and more large section engineering programs come out,especially the large span laneways in mines.As the depth of mine is deeper and deeper,it is more important to support the large span laneways.In recent years,the use of anchorage cables are more and more popular in underground geotechnical engineering,however,there are few people to do the research on reducing span with them.It is being proved that using cables could realize reducing span for roofs in deep and large span underground through similar material simulation test and numerical simulation experiment,which has great realistic significance.
