深部大采高综采面巷道超前支护技术研究

摘要

Taking the No. 1242 (3)deep fully mechanized mining face with large mining height in Xieqiao Coal Mine of Huainan Mining Group for example,the type and supporting in-tensity parameters and supporting length of forepoling were elaborated,and the ZQL2 × 4000/27/56 type forepoling was adopted. Based on the site actual conditions,the rationality of forepol-ing application was analyzed.%以淮南谢桥煤矿深部大采高1242(3)综采工作面为例，阐述工作面斜顶巷道超前支护支架的架型、支护强度、支护长度等，巷道超前支护采用 ZQL2×4000/27/56支架，通过现场实际情况分析了超前支架应用的合理性。
