8号煤试采工作面集中回风巷支护安全技术

The support safety technology of concentrated return air roadway in 8# coal mining face

在矿建施工8号煤试采工作面集中回风巷期间,采用何种支护形式对提高施工安全、进度显得尤为重要。主要介绍了在临时支护下适当变更支护形式的施工方法,即优化顶板锚索、W型钢带、金属网、加强锚索配合钢带的规格、数量及喷混凝土联合支护形式,达到安全高效、节约成本的目的。

During the entralized return air roadway of mines construction of 8# coal mining face,using what kinds of support forms were particularly important to improve the construction safety,progress. This paper mainly introduced the construction method of properly changing the support form under temporary support,that is,optimization of the roof anchor cable,W-shaped steel strip,metal mesh,reinforcing the specification,quantity of anchor cable with steel strip and shotcrete combination support form,so as to achieve the goal of safety,efficiency and cost saving.
