摘要/Abstract

摘要： 以甘肃省华亭矿区为研究对象，通过离散元UDEC数值模拟建立7种不同采放比工况，针对优化采放比、适当提高综放工作面回采率后安全回采的可行性问题进行研究，得出采放比为1∶2.5的工况为最优方案，提高回采率的同时保证了安全回采的可行性，为相似煤层综放工作面合理采放比的确定提供了一定依据。

关键词: 综放工作面, 采放比, UDEC离散元

Abstract: Taking Huating Mining Area in Gansu Province as the research object，the mode under seven different mining-caving ratios is set up with UDEC discrete element method to study the feasibility for safety mining under the optimized mining-caving ratio and the improved mining recovery.It is concluded that the mining-caving ratio of 1∶2.5 is optimal，and it is feasible for the safety mining as the recovery is improved.It provides a certain basis for determining a reasonable mining-caving ratio for similar fully-mechanized caving faces.

Key words: Fully-mechanized caving face, Mining and caving ratio, UDEC Discrete element method
