單體液壓支柱為外供恒阻式單體液壓支柱，它可以與各種頂梁配合，也可以作主柱使用？晒┡诓晒ぷ髅嬷ёo頂板使用，也可做其他臨時性支護使用。
The single hydraulic prop for the external supply of constant resistance type single hydraulic prop, it can be matched with various top beam, can also make use of column. For the blasting mining face supporting the roof, also can do other temporary supporting the use of.
單體液壓支柱適用于煤層傾角小于25度--35度的傾斜煤層回采工作面，所適應的煤層頂底板條件是：頂板落后不影響支柱的回收，底板不宜過軟，支柱壓入底板深度不惡化底板的完整性，否則應加大底座。
The single hydraulic prop for coal seam dip angle is less than the inclined coal seam mining working face 25 degrees --35 degrees, the adaptation of the coal seam roof and floor conditions is: the roof behind does not affect the pillar recovery, the bottom should not be too soft, integrity pillar pressure into the floor depth is not deteriorated plate should be added, or large base.
在煤質較松軟的炮采工作面內使用時，對活柱體鍍層表面采取保護措施，以防崩壞。支柱與木頂梁配合或做點柱使用時，應將頂蓋換成柱帽，以免損壞木梁。
Within the mining face in coal more loose cannon, to take measures to protect the active column body surface coating, to prevent the collapse. Pillar and the wooden bar with or do some column when in use, should be changed into the column top hat, so as not to damage the wooden beams.
Pillar according to liquid and liquid, divided into the external supply of liquid type (referred to as the external injection type) and for the liquid type (referred to as the injection type) pillar.
According to different pillar working stroke, divided into single telescopic (Dan Hangcheng) and the double telescopic prop (Shuang Hangcheng) pillar, in does not indicate the travel characteristic, for single telescopic prop.
The pillar by the use of different materials, is divided into ordinary steel pillar, the pillar of high titanium alloy, aluminum alloy, stainless steel pillar pillar, in does not indicate the material characteristics, is a steel pillar.
Pillar can be divided into piston plunger suspension pillar and pillar two categories according to the structure form. Piston type pillar according to the working stroke is divided into single and double telescopic prop expansion. Plunger suspension strut using water medium, which belongs to the "environmentally friendly" pillar.
每個規格可替代傳統活塞式單體支柱2-4個規格，減少了由于工作面采高和巷道受頂板、底板移進量的變化需要換不同型號單體支柱的頻次，降低了工人勞動強度和支柱額外備用數量。
支柱無承載焊縫，同時支柱采用懸浮式技術原理，高壓液產生的懸浮力直接作用在頂蓋端，達到工作阻力的五分之四，立柱受力僅為五分之一，大大提高了支柱支護的穩定性和偏載能力。
由于結構上的改進，避免了因內泄漏造成的支柱虛頂、脫頂情況，支柱一旦泄漏，在井下現場用肉眼直接就能檢查出，可隨時更換支柱；采用密封補償和密封漲緊技術原理，頂板來壓越大，密封面配合越緊密，越不易泄漏。
整體結構簡單，使用壽命長；操作方便，易于維護，能夠大大降低支柱升井及維修率。
