简单介绍了美国的长壁开采概况、矿山支护评估软件、巷道支护、锚杆支护要点和长壁面收尾硐室的应用。这些矿山支护软件涉及到盘区及煤柱设计和稳定性评估、多煤层开采影响、锚杆支护评估、柱式支护设计和评估、顶板分类等。在巷道支护方面，介绍了单位长度的锚固力和复杂地质条件下美国流行的辅助和柱式支护。长壁收尾硐室的实施一方面加快了工作面的安全搬家速度，另一方面也扩展了无机粉料材料的应用。
簡單介紹瞭美國的長壁開採概況、礦山支護評估軟件、巷道支護、錨桿支護要點和長壁麵收尾硐室的應用。這些礦山支護軟件涉及到盤區及煤柱設計和穩定性評估、多煤層開採影響、錨桿支護評估、柱式支護設計和評估、頂闆分類等。在巷道支護方麵，介紹瞭單位長度的錨固力和複雜地質條件下美國流行的輔助和柱式支護。長壁收尾硐室的實施一方麵加快瞭工作麵的安全搬傢速度，另一方麵也擴展瞭無機粉料材料的應用。

This paper introduced general situation of long-wall mining, evaluation software of mine supporting, roadway supporting, key point of anchored-bolt supporting and application of dismantlement cavern in long-wall mining face. mine supporting software includ-ed coal-pillar design and its stability evaluation, influence of multi-coalseam mining, anchored-bolt supporting evaluation, supporting design and evaluation, and roof classification. In roadway supporting, anchored force per unit length, and auxiliary and pillar support-ing widely used in U. S. under complex geological condition. Application of dismantlement cavern in long-wall mining improved disman-tlement speed and extended utilization of inorganic powder.
