深井煤巷锚索支护机理及其工程应用研究

结合高地应力、复合顶板等复杂地质条件，研究了深井条件下煤巷锚索采用小孔径、施加高预应力的结构形式和施工工艺，工程实践表明，该技术是解决深井高应力软岩巷道、大断面交岔点等支护难题的有效途径。

Application research deep well coal roadway anchor support and its project

Combining with the complex geological conditions of high ground stress and compound roof, the author studies the coal roadway anchor adopting structure form and construction technology of small aperture and imposing high prestress in the condition of deep well, project practice proves that, this technique is effective way of solving the supporting difficulties, such as high prestress soft rock roadway of deep well and the large section intersection.
