摘　　要：采煤工作面进风巷和回风巷连接处称为端头,是采煤工作面十分重要的顶板控制地段,工作面开采后承受工作面超前支撑压力的作用使两巷顶板大量下沉,甚至发生破碎、局部垮落;机头、机尾和其他设备体积较大,在移动设备时经常撤柱、支柱,反复支撑顶板,使得顶板更加破碎,因而工作面上下端头出口容易发生冒顶事故,是事故多发地段,如果再有基本顶来压的影响,其危险性就更大.所以对这地段顶板控制的好坏直接影响工作面的正常生产,必须加强支护,进行特殊管理.The junction of air inlet roadway and return roadway of coal mining face is called end,which is a very important roof control section of coal mining face.The nose,tail and other equipment have a large volume,and when the equipment is moved,the column and pillar are often removed and the roof is repeatedly supported,which makes the roof more broken.Therefore,roof caving accidents are easy to occur at the upper and lower end exits of the working face.It is an accident prone area.Therefore,the roof control of this section directly affects the normal production of the working face,so it is necessary to strengthen the support and carry out special management.

关 键 词：平行巷道走向 架棚支护 垂直巷道走向 巷道中线
