通过对岩石力学参数的测试,分析了吕家坨煤矿深部岩体的力学特征和水化对其影响程度,深部岩石巷道变形失稳机理,针对性的给出了支护方案,并利用有限差分数值软件(FLAC3D)对支护和未支护条件下的巷道变形进行了数值模拟,验证了支护方案的可行性,为吕家坨煤矿深部岩石巷道的支护工作提供了依据。
Through the testing of rock mechanics parameters, the mechanical characteristics of deep rock mass in Lujiatuo coal mine and its influence degree on hydration are analyzed. The deformation and instability mechanism of deep rock roadway is analyzed. The supporting scheme is given and the finite difference The software FLAC3D is used to simulate the deformation of the roadway under the conditions of support and unsupported. The feasibility of the support scheme is verified, which provides a basis for the support work of deep rock roadway in Lujiatuo Coal Mine.
