Study and Application of Three-step Supporting Design Method in Coal Roadway Renliang Shan1, a, Xiangsong Kong1, b, Jijun Zhou 2, c, Wenfeng Zhao 1, d, Yu Tao 1, e, Zhen Wei 1, f 1School of Mechanics and Civil Engineering, China University of Mining and Technology, Beijing 100083, China 2Department of Geotechnical Engineering, China Institute of Water Resources and Hydropower Research, Beijing 100048, China asrlcumtb@163.com, bsuihan555@126.com, czhoujijun99@126.com, dzwfcumtb@163.com, etycumtb@163.com, fwzcumtb@163.com Keywords: coal roadway; supporting design; theoretical calculation; numerical simulation; field monitoring.
Recently, most of mine projects just adopt engineering analogy method so that roadway deformation can not be effectively controlled.
Engineering situations The 3# coal seam roadway in Guandi mine is researched.
From the 3 # coal seam roadway engineering situation, H is 3m, φ is 32° , L1 is 0.1m, L3 is 0.6m, then it can be got that the sidewall bolt length L ≥2.3629m.
