摘　　要：介绍了益新公司三水平边界区18-2层右块工作面回风道煤巷采用煤体组合梁喷碹支护方式的一些作法。通过对围岩变形量的观测,证实在厚煤层中,只要选择合理的支护参数,在技术和经济上,采用煤体组合梁喷碹支护方式都优于架棚支护方式。This article introduces some methods of support and protection by using groups of steel girders shotcreting, in ventilation road, the right working area, the third level boundary area 18^-2 bed, Yixin Company. Through observating to distortion quantity of wall rock, conform that there is a better way of supporting technically and economically than ceiling support if selecting reasonable support parameter of using groups of steel girders, in thick coal bed.
