中文摘要：

针对赤峰红岭铅锌矿多年开采遗留下的80个未处理的采空区问题，通过对该矿山工程地质调查、矿岩力学试验，获取了表征矿山岩体质量的多种指标．依据获取的矿岩力学指标，利用Mathews稳定图法计算出试验采空区的稳定数和水力半径，并通过重新绘制的Mathews稳定图和等概率图的合成图，评价出采空区的稳定性以及稳定概率．利用FLAC3D对试验采空区进行数值模拟，结果与利用Mathews稳定图法评价的结果一致．对不稳定采空区进行了参数优化，并对不稳定采空区提出了支护措施．可通过该方法对红岭铅锌矿所有采空区进行评价，并可为类似矿山提供参考．

英文摘要：

There are eighty unprocessed mined-out areas in Hongling lead-zinc ore for years of mining. In order to evaluate the stability of the goafs, several kinds of indexes representing the engineering quality of rock mass in mines were acquired by the survey of engineering geology and the ore-bearing rock mechanics experiments. According to the acquired ore and rock mechanics index, the stability number and radius of hydraulic in testing goaf were calculated using the Mathews stability graph method. And stability and probability of the testing goaf were evaluated by rendering synthetic map including the isoprobability contours and the Mathews stability graph. The testing goaf was simulated with FLAC3D, and the results agreed well with the results by using the Mathews stability graph method. The parameters for unstable goaf were optimized, and some supporting measures for the unstable goaf were proposed. This method can be used to evaluate all goafs in Hongling ore and provide reference for the similar mines.
