摘要
为进一步提升巷道的掘进效率,从优化锚杆支护参数出发,以某矿31506工作面为研究对象,在对其顶底板条件分析的基础上,以顶板锚杆支护参数为例,通过理论计算初步得出支护参数,而后通过数值模拟手段最终确定支护参数,并对工作面顶部和两帮的锚杆支护参数进行优化。
In order to further improve the tunneling efficiency,starting from the optimisation of anchor support parameters,taking 31056 working face as the research object,based on the analysis of its top and bottom plate conditions,taking the anchor support parameters of the top plate as an example,initially deriving the support parameters through theoretical calculations,and then determining the support parameters by means of numerical simulation,and optimising the anchor support parameters of the top of the working face and the two gangs.
