为满足煤矿工作面高产安全生产,转变坚硬顶板岩体的力学特性,控制顶板悬露的面积,避免大面积顶板来压有重要价值。因为坚硬顶板跨落后矿压显著加大,一次跨落的高度大、面积大,同时伴有明显动压冲击,因此在基本顶来压之前需要做好顶板处理。本文简要介绍特厚煤层综采放顶煤条件下坚硬顶板的相关处理技术。 In order to meet the requirement of high-yield and safe production in coalface, change the mechanical characteristics of hard roof rock mass, control the area of ​​roof suspension and avoid the great value of roof pressure. Because the hard roof across the post-mine pressure is significantly increased, the height of a cross-large, large area, accompanied by a significant dynamic pressure shock, so the basic top pressure to be done before the roof treatment. This article briefly introduces the relevant treatment technology of the hard roof under the condition of fully mechanized caving coal in the thick seam.
