礦用土工格柵在煤礦工作中也稱作煤礦井下用雙向拉伸塑料網假頂，簡稱假頂網。礦用土工格柵是專門為煤礦井下回采工作面假頂支護和巷道護幫支護設計制造的，是采用幾種高分子聚合物并填加其它改性劑，經加熱，擠壓，成型，沖孔，拉伸，定型，卷取等工序制造而成。礦用土工格柵與金屬紡織網，塑料編織網相比，具有重量輕，強度大，各向同性，抗靜電，無腐蝕，阻燃的特點，是一種新型煤礦井下支護工程及土木工程用網狀格柵材料。
Mine geogrid in coal mine work is also called biaxial tension plastic net false roof, referred to as false roof net. Mine geogrid is specially designed and manufactured for false roof support and roadway support in www.penwuganzaojii.cnwww.gangchensu.cnwww.chenban.net.cnwww.taocichenban.cnunderground www.zhutiezhamen.net.cnwww.buxiugangwanguan.cnmining face. It is manufactured by heating, extrusion, forming, punching, stretching, finalizing and coiling with several kinds of polymer and other modifiers. Compared with metal textile mesh and plastic woven mesh, mine geogrid has the characteristics of light weight, high strength, isotropy, antistatic, non-corrosive and flame retardant. It is a new type of mesh material for underground support engineering and civil engineering in coal mine.
礦用土工格柵主要用于煤礦井下回采工作面假頂支護工程，礦用格柵亦可用作其它礦山巷道工程、邊坡防護工程、地下土建工程和交通道路工程的土石錨固、加強的材料，礦用格柵是塑料紡織網的最佳替代產品之一。
Mine geogrid is mainly used for false roof support engineering in underground mining face of coal mine. Mine geogrid can also be used as earth-rock anchorage and reinforcement material in other mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering. Mine geogrid is one of the best substitutes for plastic textile network.
