对煤矿巷道顶板实现有效控制,是全世界煤炭科技面临的重大课题之一。随着开采深度的不断增加,矿山压力显现越来越复杂,使巷道顶板管理问题成为直接影响煤炭生产的重要因素。因此,世界各国都投入了大量的人力、物力来从事适应于各种复杂地质条件下的顶板控制技术的研究。近儿年来煤矿巷道顶板控制手段得到了较快的发展,其中锚杆支护技术的发展尤为显著,现将其中某些进展作简要评述。
It is one of the major topics for coal science and technology in the world to effectively control the roof of coal mine roadway. With the continuous increase of mining depth, the mine pressure appears more and more complex, making the roadway roof management issues an important factor that directly affects the coal production. Therefore, all countries in the world have devoted a great deal of manpower and material resources to the research of roof control technology adapted to various complicated geological conditions. In recent years, roof coal mine roadway control measures have been developed rapidly, of which the development of bolt support technology is particularly significant, some of which are briefly reviewed.
