6、计条件：工作面长度150米；倾角15°；煤层平均厚度2.5米；顶板中等稳定；截割阻抗A=230N／mm；煤层的普式系数f=4。2、任务和要求（1）确定采煤机、刮板运输机、液压支架的型号和参数的验算。（2）各设备匹配尺寸和参数的验算，完成一综采设备之间的配套尺寸关系平面布置图。二、选型的基本原则1、采煤机（1）采煤机必须满足煤层开采厚度和煤的切割阻力的需要，要与煤层的倾角向适应。（2）采煤机以最小的电耗获得最大的采煤速度即生产能力，以获得最大的块度。（3）要考虑与支架和运输机配套，与支架移置速度和运输机运煤能力适应。（4）具有外喷污灭尘装置以及

7、防滑装置。.专业.整理.下载可编辑（5）机身所占空间较小，对薄煤层开采尤为重要。2、运输机（1）要满足工作面长度和倾角对于运输机铺设长度和稳定性的要求（2）运输机必须与采煤机能力相适应，要保证采煤机效能的发挥。（3）要与支架和采煤机配套（4）能在正常状态下随采煤机之后适当弯曲，并配有清扫浮煤装置，并使移置液压支架和拖动电缆方便。3、液压支架（1）要顶的住，它的初撑力和工作阻力要适应直接顶和老顶岩层移动所产生的压力（包括二次来压），使控顶区的顶板下沉限制到最小程度。（2）要移的走，它的结构形式和支护性能，要适应直接顶下部岩层冒落特点，尤其要注意

8、顶板在暴露面尚未支护的情况下的破碎状态，要尽量保持该处顶板的稳定性。支架底座要适应底板岩石抗压强度，以防底软而使支架陷入底板。（3）要满足通风和行人的要求，以及要和
