本文以甘肃华能华亭煤业集团公司东峡煤矿37220工作面为工程背景，采用相似模拟实验、理论分析、数值模拟和工程实际相结合的方法，对急斜煤层倾斜分层长壁综放煤岩移动规律、顶板破断分布规律、矿山压力分布规律、顶煤放出规律及工作面支架的稳定性进行了系统的研究，得出了一些有价值的成果，对于指导类似条件煤层的开采具有实际意义。 利用相似模拟实验，研究了急斜煤层倾斜分层长壁综放过程中，煤岩在走向和倾向两个方向的垮落规律及矿压显现特征；采用可调角散体放煤支架，研究了不同倾角、放煤顺序及放煤方式，对顶煤的放出规律、含矸率和支架稳定性的影响。 应用有限差分计算程序(FLAC3D)，模拟分析三维综放工作面的宏观力学作用过程，研究了综放面开采的整体推进过程中，工作面煤岩破断运移规律；应用散体元计算程序（PFC2D），对散体顶煤和部分破碎直接顶的落放过程、落放规律及不同放煤步距连续推进模式下的煤损特征等进行模拟分析。 根据现场工作面地质条件建立支架受力模型，得出了支架在自重状态下的滑移临界角为17°，倾倒临界角为37°，要使支架在工作面不发生滑移，初撑力不得小于167.35kN。工作面采取“倾斜-圆弧过渡-水平”布置方式，改变了支架的受力状态，增加了设备的稳定性。 通过模拟实验、数值计算、理论分析和现场观测，总结了急斜煤层倾斜分层走向长壁综放工作面矿山压力分布规律、煤岩破坏分布特征，以及顶煤放出规律，对于急倾斜煤层走向长壁综放开采煤岩控制，具有实际的应用价值。

The paper has taken the East Gap coal mine of Gansu Huaneng Huating coal industry group company in 37220 working face as the engineering background,using the method of similarity simulation experiment,theoretical analysis,numerical simulation and engineering practice combined to do system research about steep seam long wall caving tilt stratified movement rule,mining coal breaking distribution,pressure distribution,roof stability of mine coal caving support rules and working face.It has obtained some valuable achievements,which has a practical significance for guiding the similar conditions of coal seam mining. Using similar simulation experiments to study the steep seams inclined stratified Long-wall release process,coal and rock in both directions and tendencies toward collapse law and Strata features; using research group developed an adjustable angle of dispersion caving bracket,studied at different inclination,caving coal order and put under way,the release of the laws of the top coal refuse content and stability of the bracket. In numerical analysis,the paper use finite difference calculation program (FLAC3D) to analysis macro mechanics process of three-dimensional analysis of fully mechanized top coal caving stope and the coal and rock breaking movement; it also use discrete element calculation program(PFC2D) to analysis the dispersion of top coal and broken part direct top drop process,drop rule and different coal caving step distance and the continuous propulsion mode of coal loss characteristics. According to the geological conditions of the site to establish stand Face force model,come to stand under the weight of state slip critical angle is 17 degrees,pour the critical angle of 37 degrees,to make the stent slippage does not occur in the face,setting load not less than 167.35kN. Face to take "tilt - arc transition - level" arrangement,change the stress state of the stent,increasing the stability of the equipment. Through similarity material experiment,numerical calculation and theoretical analysis,summarized the steep seams inclined stratified put Long-wall mining stope pressure distribution,distribution of coal and rock damage,and top coal caving law,the results of Steep Seam caving technology in theory,for Steep Seam coal and rock disaster control,with the actual value.
