摘要
山西三元福达煤业煤炭资源储量少科学合理地确定煤柱宽度以减少煤柱损失量对其具有重要意义,为了在工作面采用沿空掘巷留小煤柱技术,因此对工作面顺槽支护方案进行优化。分别对锚杆的预应力、锚杆密度、锚杆长度、锚固方式、锚杆角度等进行了模拟分析,对工作面巷道的支护提出了改进措施。
The Sanyuan coal mine, which is reserves of coal resources, so determine pillar width scientificly is of great significance to it. In or-der to adopt gob-side entry driving, therefore exert scheme optimization on working face supporting. Simulation analysis the anchor prestress,bolt consistency, anchor length, anchoring typeand anchor angle, put forward the improved measures of working face supporting.
