摘要
采煤工作面上出口作为工作面压力显现集中区之一,不但是人员、设备、材料的集中区,还是人员、设备和材料进出工作面的交接口。上出口行人防护对人员和设备安全的至关重要。针对上出口顶板倾角大、巷道高度变化大、高帮与巷道底板高差大、空顶面积大等问题,研究一种新型行人防护支架,以达到保证行人安全的目的。
The upper exit of the coal mining face is one of the concentrated areas of the pressure development of the working face.It is not only the concentration area of personnel,equipment and materials,but also the interface of personnel,equipment and materials entering and leaving the working face.The pedestrian protection at the upper exit is crucial to the safety of personnel and equipment.Aiming at the large tilt angle of the roof,the large change of roadway height,the large height difference between high wall and roadway floor,and the large empty roof area,studied a new type of pedestrian protection support for the purpose of ensuring the safety of pedestrians.
