The roof support design of 31101 fully mechanized coal face of Nalinhe No.2 mine

论文以内蒙古纳林河二号矿井为工程背景,分析了31101综采工作面煤层赋存及顶底板情况,根据分析和计算对支架进行选型,最终选择中煤北京煤机集团ZY13000/28/62D双柱掩护式工作面液压支架及其配套的ZYT13000/26/55D端头、ZYG13000/28/62D过渡支架。实践结果表明,所选支架都能满足支护载荷、支护高度等各项要求,保证了矿井的高效安全生产。

The thesis takes Nalinhe No. two mine of Inner Mongolia as engineering background, analyzes the occurrence of coal seam and roofand floor of 31101 fully mechanized coal face. According to the analysis and calculation of the stent selection, the final choice of the ChinaCoalBeijing Coal Mining Machinery Group ZY13000/28/62D hydraulic support with double column cover and its supporting ZYT13000/26/55Dend,ZYG13000/28/62D transition bracket was finally chosen. The practical results show that the support can meet the requirements of supportingload, support height, and ensure the safe production of the mine.
