基于综放端面控制的支架支护参数研究

Research on Parameters of Support Based on Control of Roof

神华神东布尔台煤矿改变开采工艺后,需要对液压支架支护参数进行优化,理论分析综放端面煤岩体片帮冒落与支架参数支架关系,运用数值模拟方法,建立综放端面煤体片帮冒顶模型,对液压支架参数与端面煤岩体片帮冒落相互关系进行模拟。结果表明支架工作阻力与梁端距是影响支架控制效果的关键参数。

According to change of the mining method,Buertai mine requests for optimization of parameters of support. Based on Geological conditions and information of rib spalling in fully mechanized mining face.A model of rib spalling in fully mechanized mining face is built by numerical simulation method to study relationship between support and rib spalling in mining face. Results showed that support force and distance between end Qf the beam influence control effect of supprot.
