某煤矿原井巷工程锚杆支护全部使用金属锚杆，施工工艺和安全效果较好，但是在综采工作面回采中，帮部金属锚杆不能被采煤机直接截割，不仅易损坏采煤机的截齿，而且极易产生火花，威胁井下安全。对工作面两巷帮部及切眼的支护设计进行优化，采取可截割玻璃钢锚杆在该巷道进行支护试验，取得了较好的效果。
某煤礦原井巷工程錨桿支護全部使用金屬錨桿，施工工藝和安全效果較好，但是在綜採工作麵迴採中，幫部金屬錨桿不能被採煤機直接截割，不僅易損壞採煤機的截齒，而且極易產生火花，威脅井下安全。對工作麵兩巷幫部及切眼的支護設計進行優化，採取可截割玻璃鋼錨桿在該巷道進行支護試驗，取得瞭較好的效果。
모매광원정항공정묘간지호전부사용금속묘간，시공공예화안전효과교호，단시재종채공작면회채중，방부금속묘간불능피채매궤직접절할，불부역손배채매궤적절치，이차겁역산생화화，위협정하안전。대공작면량항방부급절안적지호설계진행우화，채취가절할파리강묘간재해항도진행지호시험，취득료교호적효과。
Original mine engineering anchor bolt support all used metal bolt,construction technology and safety effect is good,but in fully mechanized mining face,the help of metal bolt cannot be coal winning machine cutting directly,not only easy to damage the coal winning machine cutting tooth,and easy to produce sparks,easy to cause gas explosion, down -hole safety threat.Face two lanes on the basis of the mine through investigation to help and to optimize the supporting design of starting cut and take cutting glass reinforced plastic anchor rod in the roadway supporting experiment was carried out,after a period of time,has certain experience,improve the work efficiency.
