煤矿生产面对着各种复杂的地质条件，作业环境随时间空间不断发生变化，要求工作面布置方式和回采方式也要不断适应这种变化。综放工作面异形煤柱条件下护巷技术的研究，就是为适应矿井在复杂环境条件下正常生产需要解决的一项技术难题。 本文从解决现场实际问题出发，针对综放工作面异形煤柱特点，研究了异形煤柱和巷道围岩应力场、位移场和破坏场分布规律；有针对性地设计和采用锚杆、锚索和临时支柱等控制措施，对需要保护的巷道在关键部位和采动影响时期进行机理明确的综合加固与控制；采用多种监测技术手段，对留巷在不同煤柱宽度处围岩的压力、变形和破坏进行了现场监测，揭示了不同宽度煤柱留巷在采动影响下沿倾斜和走向方向岩层压力分布、巷道围岩移动变形与破坏的演化规律，取得了良好的支护效果，并为今后类似条件下的工程设计、施工和管理提供了科学依据。

The coal mine production faces various complicated geology conditon,working environment changes continuously with time and space,so it is necessary to make the way of face layouting and mining to adapt this kind of variety.The purpose of researching protecting entry techniques under anomalistic pillar conditions in Fully Mechanized Caving Faces is to solve the technical problems that making the mine to product properly on complicated conditions. Based on solving the field problem,and aiming at the characteristics of anomalistic pillar,the distributional regularities of stress,displacement and failure area are researched;Through point design and employing some control methods,such as cable,anchorage cable and temporary brace etc.,the critical region of some openings,which are needed to protect during the caving influence times,are strengthened and controlled comprehensively depending on sxplicit mechanism;the stress,strain and failure of surrounding rock,belonging to reserved entry near the anomalistic pillar,are surveyed by multi-survey techniques in the field.and the results indicate the distributional regularities of tress along the dip and strike,and the space-time evolvement regularities between distortion and failure in the surrounding rock of different width pillar reserved entry under the caving influence.This techinque proved in the practice can achieve sateisfying support effect, and also afford a seientific accordance to the project design,construction and management under similar conditions.
