煤矿深部井底硐室开挖诱发临近巷道围岩失稳严重影响矿井建设和安全生产。基于深部斜井围岩稳定性力学分析，揭示在与斜井相交叉的巷道和硐室开挖产生的扰动应力影响下斜井围岩变形破坏机理，对深部巷道围岩控制及矿井安全高效开采具有重要意义。 论文研究以玉溪煤矿深部斜井受与之交叉的巷道和硐室开挖对围岩变形的影响为工程背景，建立了考虑空间几何关系的巷道围岩力学模型，并借助计算机辅助工程程序(CAE-Midas GTX NX)和三维有限差分程序(FLAC3D)构建了数值模型，采用理论分析与数值模拟相结合的方法，分析得出在扰动应力影响下深部斜井交叉巷道及硐室围岩应力与变形规律，揭示深部软岩斜井变形破坏机理，提出适于玉溪煤矿深部斜井底鼓治理方案，并应用于现场加固工程。研究结果表明：主斜井区域地质赋存条件特殊性表现在其夹持于向斜与背斜地质构造之间，水平构造应力成为影响围岩变形的主要因素；建立围岩垂直应力(FV)与水平应力(FH)的平衡判据方程，得出机头硐室与主斜井交叉位置水平应力(FH)占主导；数值模拟表明巷道围岩主应力区位于模型中开挖斜井两帮底角，成为引起底鼓的主要原因。 针对玉溪煤矿底鼓治理问题，提出注浆锚索与钢筋混凝土联合治理方案，现场应用效果显著。这为进一步研究深部穿层斜巷受掘进扰动影响巷道围岩变形的预测与控制提供了有效方法。

Coal-rock instability of the tunnel in the coal mine, due to deep inclined shaft and underground openings, has a strictly influence on the mine construction and the safety mining. Surrounding rock deformation and failure mechanism of inclined shaft and openings, under the circumstance of the dynamic stress disturbance, can be reveal by using of mechanic analysis, which is significant for the stability controlling of rock mass in the deep tunnel. The paper focus on research background of considering coal and rock mass deformation of the deep inclined shaft being effected on crossing tunnel and underground openings. Comprehensive methods of theoretical analysis and numerical simulation have been used to study coal-rock stability of deep inclined shaft and underground openings. Mechanical model and numerical model have been built by using of the Computer Aided Engineering(CAE) software of Midas GTX NX and the Three Dimension of Fast Lagrangian Analysis of Continua(FLAC3D) basing on coal-rock constitutive relations. Stress distribution and deformation regulations, under the circumstance of excavation stress of deep inclined shaft and underground openings, also have been revealed. Finally, floor control method has been presented and applied in Yuxi Coal Mine. Results show that horizontal stress (FH) is main factors of rock deformation and special characteristics of sandwiching between syncline and anticline. Balance equation relations between vertical stress(FV) and horizontal stress(FH) is conducted with revealing fact that FH is dominant at crossing site of the main inclined shaft and underground opening for head chamber. Numerical simulation show that main stress section located at bottom sides of inclined shaft. Aiming at floor control problems of Yuxi Coal Mine, methods of combining grouting anchor cable with ferroconcrete has been applied in situ. It has an obviously effective control about floor deformation. These research results would provide an effective guidance for rock deformation prediction and controlling of deep inclined shaft and underground openings.
