煤矿综采工作面端头支架设计及应用研究

Fully Mechanized Coal Mining Face End Bracket Design and Applied Research

煤矿开采矿压显现是采动应力集中现象。综采工作面端头是工作面与上下平巷贯通地点,工作面端头空间相对要大,以便安放与采煤机装备相配套的设备。因此,工作面端头受采动应力影响较大,也是强矿压显现地点,需要加强支护才能达到保证安全的目的。从端头支架的结构、液压控制系统和主要参数的确定方面进行研究,达到加强支架的支护强度目的,进而保证工作面端头支护稳定,保障煤矿安全生产,提高生产效率。

Coal mining pressure behavior the stress mining face end face and the upper and lower drift concentration mining. Coal mining mechanized through the location, the face end space is relatively large, in order to be placed with shearer equipment supporting equipment. Therefore, the face end by mining pressure greater impact, but also strong mining pressure show location, the need to strengthen the support in order to ensure safety purposes. From the the tip bracket structure, hydraulic control system and main parameters determining reached to strengthen the supporting strength of purpose of the bracket, thereby ensuring the face end support retaining stability, protect the coal mine production safety, improve production efficiency.
