为了提高煤炭回收率，在综放开采中沿空掘巷技术应用逐渐增多，而如何确定合理的沿空巷道位置，有效控制其围岩应力，并选择合理的支护方法与支护参数，已成为保障沿空巷道围岩稳定性的关键所在，也是目前巷道围岩控制及支护技术研究的热点。 论文以神华宁煤集团石炭井二矿21053综放工作面沿空掘巷为工程背景，针对综放沿空巷道煤柱留设、巷道掘进及支护过程中存在的问题，采用数值模拟、工程类比、理论计算和现场试验研究相结合的方法，对综放沿空巷道围岩稳定性及其控制技术进行了初步探讨和研究。 依据21053工作面的实际情况，应用FLAC-3D软件进行数值模拟，研究了不同保留煤柱宽度和支护参数对沿空巷道围岩稳定性的影响，探讨了采空区侧向支撑压力分布规律，得到了掘进及回采期间沿空巷道围岩应力、应变非对称性变化规律，并据此提出了21053综放工作面沿空掘巷锚网索支护设计方案。 结合21053工作面异形煤柱特殊条件，采用数值模拟和现场监测、试验相结合的方法，分析了不同条件下沿空巷道围岩稳定性及其破坏特点，根据围岩塑性区扩展情况，将沿空巷道掘进及回采期间煤柱内是否存在稳定的弹性核作为评价煤柱稳定性的标准，综合考虑巷道稳定性、支护强度、支护及维护成本等因素，确定了试验工作面合理的保留煤柱宽度为8m。 通过数值模拟、理论分析、现场综合监测与工业试验所得出的沿空巷道应力应变规律、煤柱尺寸和锚网索支护方案，对同类工程具有一定的参考价值。

The application of gob-side entry driving became more and more important in fully-mechanized caving in order to enhance coal percentage extraction. The design of the rightness position for gob-side entry driving and effective supporting method have been turned into the key technology which was used to co control the stress and ensure the stability of surrounding rock along caving roadway. Based on the engineering background of 21053 work face in the Shi Tan Jing second Coal Mine of Shenhua Ningxia coal company, the problems of coal pillar designing, laneway excavating and supporting are discussed in the paper. The stability of the surrounding rock along fully-mechanized caving roadway and its controlling technology are studied by using the methods that synthesizing project analogy method, theoretical computation, field experiment and numerical simulation. The effect to stability of the surrounding rock along caving roadway, which produced by pillar width and supporting parameter ,has simulated and studied respectively in the process of laneway driving using FLAC-3D. The distribution of confining pressure which caused by mine stope was discussed. The distribution of stress in surrounding rock during the laneway driving and caving has been obtained. The extension of plastic zone has been used to appraise the stability of pillar during laneway driving. Based on the anomalous pillars, it also analyzed the safety, driving speed, support intensity and cost etc, and choosed the reasonable pillar width as 8m. The effect to stress, deformation and plastic in surrounding rock, which caused by the supporting, has been analyzed by using the orthonormal numerical simulation. And the force and failure mechanism of the cables have been studied, too. It also designed the bolt-mesh-cable supporting for the laneway in 21053. By contrasting the data of numerical simulation and field experiment, It analyzed the stability of the surrounding rock and its destroyed modality. It was scientific and effective that controlled the surrounding rock in fully-mechanized caving roadway by laneway layout study and bolt-mesh-cable supporting. The conclusion could be used in the similar project.
