內(nei)柱式單(dan)體(ti)液壓支(zhi)柱是一種新環保(bao)型的支(zhi)護裝備(bei),既可(ke)與金(jin)屬(shu)鉸接頂梁(liang)配(pei)套用(yong)(yong)于普采(cai)和炮(pao)采(cai)用(yong)(yong)工(gong)作(zuo)面支(zhi)護頂板以及綜采(cai)工(gong)作(zuo)面支(zhi)護端頭,也(ye)可(ke)單(dan)獨做點柱或其它臨時性支(zhi)護用(yong)(yong)。
內柱式(shi)單(dan)(dan)體液壓支(zhi)(zhi)柱是(shi)一(yi)種新環(huan)保型的支(zhi)(zhi)護(hu)裝備,既(ji)可與金屬鉸接頂(ding)梁(liang)配套用于(yu)普采(cai)和(he)炮采(cai)用工作面(mian)支(zhi)(zhi)護(hu)頂(ding)板以及(ji)綜采(cai)工作面(mian)支(zhi)(zhi)護(hu)端頭,也可單(dan)(dan)獨做點柱或其(qi)它臨時(shi)性支(zhi)(zhi)護(hu)用。
內(nei)柱式(shi)單(dan)體液壓支柱適(shi)用(yong)于煤(mei)層傾角小于25度--35度的(de)(de)傾斜煤(mei)層回(hui)采(cai)(cai)工作(zuo)面(mian)(mian),所(suo)適應的(de)(de)煤(mei)層頂(ding)底(di)(di)板(ban)(ban)條(tiao)件是:頂(ding)板(ban)(ban)落后不(bu)影響支柱(zhu)(zhu)的(de)(de)回(hui)收,底(di)(di)板(ban)(ban)不(bu)宜過(guo)軟,支柱(zhu)(zhu)壓入底(di)(di)板(ban)(ban)深(shen)度不(bu)惡化底(di)(di)板(ban)(ban)的(de)(de)完整性,否(fou)則應加大底(di)(di)座(zuo)。在煤(mei)質較(jiao)松軟的(de)(de)炮采(cai)(cai)工作(zuo)面(mian)(mian)內使用(yong)時,對活(huo)柱(zhu)(zhu)體鍍層表(biao)面(mian)(mian)采(cai)(cai)取保(bao)護措施,以防崩壞。支柱(zhu)(zhu)與木(mu)頂(ding)梁配合或做點柱(zhu)(zhu)使用(yong)時,應將(jiang)頂(ding)蓋換成柱(zhu)(zhu)帽,以免(mian)損壞木(mu)梁。
