摘要
针对某矿煤层巷道锚固支护特征,用有限差分方法进行了数值模拟研究。模拟结果表明,有限差分方法能够较好地模拟煤层巷道锚固煤(岩)体变形特征和锚杆(索)受力特征。为同类煤矿巷道锚固岩体数值模拟提供了技术参考。
Pointing to the characters of coal roadway bolting support in one mine, finite-difference method was used to make a numerical simulating research. Simulation result shows that finite-difference method can consider displacement in rock （or coal） and force in bolt well,and the result can be a reference to the decision of the same kind of support project.
