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。

The text obtains some data that caving span of immediate roof is 30m, caving span of main roof at first weighting is 42m and caving span of main roof at periodic weighting is 14m. Mining influence range is determined about 40m through numerical modeling, namely about three advance pillars were in the range of mining influence.

利用数值模拟得出煤柱采场直接顶的垮落步距为30m，老顶的初次来压步距为42m，老顶的周期来压步距为14m；通过模拟超前支承压力，确定了采动影响范围约为40m，即采场超前的三个煤柱都在影响之内。

Meantime, based on the migratory characteristics of main roof fall, the main roof were divided into some plate group and plate group mechanical model was established for main roof with different crannies and fault ages.

同时针对深部采场顶板岩体垮落具有局部、分段、迁移的时空特征，将长壁工作面采场顶板划分成若干个相互铰接的薄板，建立了薄板组力学模型。

As a folding roof cover extending throughout the entire length of the roof, the roof structure may be opened both from the front and from the rear, letting either fresh air or warm sunshine into the car - or both, depending on the driver's and passengers' wishes.

作为一个折叠上盖扩大到整个长度的屋顶，屋顶结构都可以打开从前线和后方，让新鲜空气或任何温暖的阳光进入汽车-或两者兼而有之，这取决于司机和乘客的祝愿。

In order to study basic roof's destruction movement that affects working face in horizontal section top coal caving in mining steep seams, this paper analyses tension of roof using elastic and thin board theory and concludes criterion of roof destruction based on long and narrow thin board.

摘要为研究急斜煤层水平分段放顶煤开采过程中基本顶破坏活动对工作面的影响，根据急斜煤层基本顶具有倾斜狭长板的特点，运用弹性薄板理论对基本顶岩层进行了拉应力分析，得出了顶板破断的判别准则，建立了基本顶初次破断后形成的&铰接结构&的力学模型。
