FUZZY MATHEMATICS MODELS ON ROCKMASS DISPLACEMENTS DUE TO OPEN-UNDERGROUND COMBINED MINING FOR THICK ORE BODY WITH STEEP DIP ANGLE
急倾斜厚大矿体地下与露天联合开采岩体移动分析的模糊数学模型

Li Wenxiu,<br>李文秀
岩石力学与工程学报 , 2004,
Abstract: The mathematical models on rockmass displacements for underground mining and slope stability are established by using fuzzy mathematics theory and applied to predict the rockmass displacements and deformations due to open-underground combined mining for the thick ore body with steep dip angle. The fuzzy mathematics method is used to determine the engineering parameters for analysis and calculation. The results of calculation can be applied to predict ground surface movements due to underground mining,and provide a theoretical basis for mining engineering design.

岩石力学中的Fuzzy数学方法

Li Wenxiu,<br>李文秀
力学学报 , 1990,
Abstract: In view of the marked "Fuzziness" in the factors that have effect on the problems of rock mechanics, the deformation failure of rock mass in mining engineering is studied by using the Fuzzy mathematical theory in the paper. In accordance with the deformation failure of rock mass in open-pit mines, by applying the theory of Fuzzy probability measures, the Fuzzy probability formula is derived for the deformation failure of rock masses, and the numerical method is given to calculate the Fuzzy probability. The practical calculation shows that the method can be applied to analyzing and studying the problems of the rock mechanics, especially the mining rock mechanics.

鲁中矿区破碎矿体开采地压测试及支护技术研究

LIU Xinqiang,LI Wenxiu,<br>刘新强,李文秀
岩石力学与工程学报 , 2008,
Abstract: 鲁中矿区地质条件复杂,地下裂隙水发育,矿体破碎难以安全采出.采场地压表现为在自重应力作用下,顶板出现拉应力破坏,导致顶板冒落.针对这种情况,开展采场地压规律的动态监测.应用钻孔应变计测量采场地应力变化,采用电子数显式收敛计量测围岩变形,得出采场巷道地压变化的一般规律,为矿山今后选择合理的开采方案和地压控制措施提供科学依据.

浅谈露天矿山边坡稳定性研究中的钻探与疏水问题
李文秀
地质与勘探 , 1985,
Abstract: 边坡稳定的重要性在矿产资源开发中,无论是金属矿或非金属矿,露天开采都占有较大的比例.在露天采矿中,边坡稳定问题一直是被关注的重要问题;尤其是金属矿山的深凹露采高陡边坡稳定问题,更为突出.当今,国内外许多露采矿边坡稳定问题,已处于急需研究解决的阶段.经大量观察,凡是发生滑坡事故的矿山,均可能在缩短露天矿的寿命,影响现场生产,或损坏设备以及危害人身安全等方面造成不良后果.现就下列矿山滑坡事故加以介绍.
模糊数学用于预测溶解采矿地面下沉
李文秀
环境科学学报 , 1990,
Abstract: 通过建立某一地面下沉值与影响下沉的诸因素间的模糊关系方程,并求解该方程,找出各指标间的模糊关系,然后将需要预计的采区下沉值的各有关影响因素指标之实测值,通过实际求得的模糊关系做模糊变换,从而可给出下沉值的最佳预计值.将理论结果与现场资料进行对比,二者吻合较好.

岩石工程学报 , 1991,
Abstract: 本文是文献的深入研究和发展。根据岩土工程中大量观测资料的统计分析,利用模糊概率测度(fuzzyprobabilitymeasures)理论,建立了具有普遍意义的岩(土)体移动模糊数学模型,并有效地用于分析地下开挖引起的地表移动。从而论证了该模型的工程适用性。本文模型在岩土力学领域形成了新的理论研究体系——模糊数学理论体系。

岩石工程学报 , 1996,
Abstract: 本文首次将模糊测度(fuzzymeasure)理论用于分析岩土边坡稳定问题。根据模糊测度理论,针对实际边坡工程问题,建立了具有普遍意义的理论分析模型,并给出了具体的数值方法。计算分析结果表明,理论值与实际情况相一致。同时也证实了模糊测度模型比已有的经典分析方法具有明显的优越性。本文方法适用于分析土质边坡及节理裂隙发育的岩质边坡等各类边坡稳定问题。
