摘　　要：以实用采场矿压理论的成果为基础，较深入地分析了综放条件下采场结构力学模型特征，讨论了放顶煤综采高效安全开采的条件问题。明确指出，采场支承压力分布出现内应力场是综放高效安全开采的客观基础；采用正确的放煤程序保证支架在高位态和高阻力状态下工作、以及采用正确的开采程序实现在稳定的内应力场掘进和维护巷道是综放工作实现高效安全的关键。Based on the practical theory of ground pressure in the workings, the characteristics are analyzed of structural mechanics in the work face, when sub-level caving method is introduced. The safe mining conditions of high efficiency production are discussed. There is an inner stress field in the abutment pressure area, which is a basis for safe mining. Correct coal drawing procedure should be followed to ensure safe working conditions of the support of high resistance. And the key to safe and high productivity production is to drive and maintain gateway in a stable inner stress field by using correct coal drawing procedure.
