摘要
针对保德煤矿在厚煤层综采放顶煤开采设计中遇到的实际问题,根据保德煤矿8#煤层赋存条件,对88300-1综放工作面进行了以支架工作阻力监测为主的现场矿山压力实测工作,通过观测及数据分析,得到了顶板来压规律和支架适应性等重要信息,为放顶煤支架的适应性评价及放顶煤工艺设计提供了指导经验。
Aiming at the actual problems of the design in fully mechanized top coal caving mining in thick seam and according the occurrence condition of No. 8 Seam in Baode Colliery, the author makes the field measurement of mine pressure for the main aspect of support working resistance monitor in 88300--1 full--mechanized top-- coal caving face, and obtains important information such as roof pressure law and support suitability by observa- tion and data analysis, which provides guidance for the evaluation of suitability of top--coal caving support and the technology design of top coal caving.
