摘　　要：针对深井综放采场过平行联络巷发生压架,采用理论分析、工程验证等方法对压架机制及控制对策进行研究,并基于"支护阻力相等"、"并行通过支架数最小"等原则建立了采场调斜角定量确定方法。得到结论:1)控顶厚度增大、控顶范围增大、顶板冲击和时间效应造成的支架载荷异常与支架并行通过联络巷导致的采场大面积来压综合作用是深井综放采场过平行联络巷压架的原因;2)通过加固联络巷顶板、快速推进等降低支架载荷和通过调斜采场避免大面积来压,可有效控制综放采场过平行联络巷发生压架;3)采场调斜角与联络巷宽度、顶板载荷、支架额定支护阻力、控顶距、中心距等有关。The mechanism and control countermeasures of support crushing within deep fully mechanized caving face through the parallel crossheading were researched through theoretical analysis and engineering verification. The method for determining slope adjustment angle was set up based on principles of equal support resistance and lower supports crossing crossheading in parallel. The following results have been obtained：1） Comprehensive action of large area weighting resulting from many supports exposing the crossheading, and support load abnormality resulting from increases of control roof thickness and face range, roof impact and time effect are the causes of support crushing within deep fully mechanized caving face through parallel crossheading;2） Effective control over support crushing within deep fully mechanized caving face through the parallel crossheading can be achieved by reducing support load with a large area through reinforcing crossheading roof, accelerating advancement, and adjusting slope mining;3） The slope adjustment angle depends on crossheading width, roof load, working resistance, face range, and center distance, etc.
