研制调阻式机械化支架乃是刨采工艺的最迫切问题之一。应用这种支架的目的就在於利用矿山压力来松动煤层边角部分,从而可提高创煤机的开采效率,靠采硬质煤来扩大其应用范围。 1MKCP型刨采机械化支架是在1MKC型支架和双段调阻系统的基础上研制的。1MKCP型支架不仅能在较大的范围内安全地改变阻力大小,而且亦能使阻力分布在一排支柱上。1MKCP支架(图1)由下列各
It is one of the most urgent problems in the development of the tuned mechanized stent. The purpose of the application of this bracket is to use mine pressure to loosen the corners of the coal seam, which can improve the coal mining efficiency, rely on hard coal to expand its scope of application. 1MKCP type planing mechanized scaffolding is 1MKC type bracket and two-stage modulation system developed on the basis of. 1MKCP-type stents not only can change the resistance size safely within a large area, but also can make the resistance distribution in a row of struts. 1MKCP stent (Figure 1) by the following
