由于煤矿掘进工作面场地狭窄、支护技术较落后、施工环境恶劣 ,实现巷道施工快速、优质、高效有一定难度 ,成为制约高产高效矿井发展的重要因素。因此 ,应用价值工程的方法 ,建立起综掘工作面设备的评价方法 ,推动综掘工作面设备优化配置 ,充分发挥设备的最大效能 ,为实现综掘工作的安全高速高效 ,提供了一种较先进的测算方法 Due to the narrow site of coal mining face, backward support technology and poor construction environment, it is difficult to achieve rapid, high quality and high efficiency of roadway construction and become an important factor restricting the development of high productivity and high efficiency mines. Therefore, the method of value engineering is applied to establish the evaluation method of equipment for fully mechanized face excavation, to promote the optimal disposition of equipment in fully mechanized face, to give full play to the maximum efficiency of equipment, and to provide a more efficient and safe working method for fully mechanized heading.
