摘　　要：合理确定液压支架支护强度,始终是影响煤矿安全生产及发展的重要因素之一。将理论研究与数值模拟相结合,以支架-围岩的相互作用为依据,分别通过经验估算法与FLAC3D数值模拟法对支架工作阻力进行研究,并结合现场实例验证方法的可行性。Reasonable determination of support strength of hydraulic supports is one of key factors which always affect the coal mine safety production. A study has been made of working resistance of supports by using methods of empirical estimation and FLAC3D numerical simulation respectively according to bonding of theoretical research and numerical simulation. And then verification of feasibility of methodology has been conducted by exemplifying field data.
