由于回采工作面端头的设备比较集中,问题多,难度大,因而许多综采工作面多年来没有广泛使用端头支架。端头支架的使用一般都是一种端头支架配一种型号的工作面支架以及固定的配套设备。由于国外引进和国产液压支架品种繁多,架型不统一,因此要配好端头支架有一定的困难。SDA型(见图1)和SDB型(见图2)端头支架就是考虑到上述原因,分析研究了国 Due to the centralized mining equipment face, the problem is more difficult, so many fully mechanized mining face over the years did not widely use the end bracket. The use of end brackets are generally a kind of end bracket with a type of face support and a fixed supporting equipment. As the introduction of foreign and domestic hydraulic stent a wide range of models are not uniform, so with a good head stent has some difficulties. For the above reasons, SDA type (see Figure 1) and SDB type (see Figure 2)
