摘　　要：现在许多薄煤层采煤机都采用开式液压控制调高系统,开式液压调高系统需使用比较大的专用液压油箱,油箱空间占整个泵站空间的60%,针对薄煤层采煤机安装空间有限的特点,采用闭式液压控制调高系统,将油箱缩小到原来1/3以下,相对增大了液压泵站的安装空间,有利于薄煤层采煤机井下安装维护。At present, open-type height adjusting hydraulic system are employed by most thin miners, However, open-type hydraulic system must own a bigger oil tank and tank holds whole pumping station space 60%. According to limited installation space of thin miner, a close-type hydraulic system is adopted, Oil tank may be narrowed down to a third of original below, which relatively increases hydraulic pumping station installation space and is helpful to underground maintenance.
