摘要
为了提高采煤工作面端头顶板支护强度,提高工作面回采率和生产效率,解决因回风端头遗煤而引发的自然发火问题,阳煤一矿8303工作面引进了ZYP12000/30/68D型过渡支架,现场应用证明该支架对解决上述问题效果良好,安全价值及经济效果显著,值得同类条件的矿井推广应用。
In order to improve the support strength of the end roof of the mining face,increase the recovery rate and production efficiency of the working face,and solve the spontaneous combustion problem caused by the coal left at the return air end,the ZYP12000/30/68D transition support was introduced into the 8303 working face of Yangmei No.1 Coal Mine.Field application proves that the support has good effect and safety value in solving the above problems.It has remarkable economic effect and is worth popularizing and applying in mines with similar conditions.
