The top coal fracture is described distinctly under the condition of different roof span and mining technology parameters. Through orthogonal experiment of numerical simulation, the rational pretreatment span of hard roof is determined, and the rational working resistance of support is selected also. As a result: the hard roof is effectively controlled not only to protect the working face but also to promote the caving of hard top coal to increase the recovery ratio.

在有效控制坚硬顶板的基础上，利用数值模拟正交试验法，研究了采高、采放比、支架阻力、放煤步距等工艺参数对顶煤压裂效果的影响规律，从而对工作面工艺参数进行优化；并根据实验所得放煤方式对块体顶煤的适应性规律，选择&两硬&综放面的放煤工艺，从而形成了系统、完善的&两硬&条件综放工艺。
