煤礦井下用鋼絲網(wǎng)骨架塑料復(fù)合管在生產(chǎn)的而過程中專業(yè)為煤炭作業(yè)打造的一種耐高壓管材，中間層是以纏繞鋼絲網(wǎng)為主，聚乙烯本身具有阻燃抗靜電，用專用熱熔膠，通過擠出成型方法復(fù)合成一體的管材，對(duì)與地下煤炭作業(yè)有良好的保護(hù)作用。
煤礦井下用鋼絲網(wǎng)骨架塑料復(fù)合管根據(jù)其不同的用途，也有不同的分類：其中最常見的有：氣體通用管(KMQ)和液體通用管(KML)
氣體通用管 CKMQ)可用于煤礦井下正壓通風(fēng)、負(fù)壓通風(fēng)、抽放瓦斯等;
液體通用管(KML)可用于煤礦井下供 水排水、噴漿等;
用于煤炭作業(yè)的管材還必須擁有較長的工作壽命和耐腐蝕特性，這樣就可以從根本上減少成本，提高管材的運(yùn)行質(zhì)量。其中常見的規(guī)格有以下幾種：
