【摘要】 针对蒲白矿务局马村矿西固村镇的复杂的地形、地质、采矿条件 ,运用动态预计理论分析确定不同的开采方案 ,并运用YHL - 12进行仿真模拟计算 ,分析在特定条件下西固村镇下煤层的开采方案。结果表明 ,运用倾斜变条带协调开采方案可以有效的控制地表移动变形值 ,减缓采动地表损害程度 ,达到保护地表建筑物的要求 ,能产生较好的技术经济效果[1] 。更多还原

【Abstract】 in according with the complex condition of the surface and underground of Macun pit in Pubai mine area,this article apply theory analysis to determining the different extraction method and apply the program of YHL-12 to numerical simulation,and optimize the above scheme. Through the above analysis and contrast,we may adopt the hading and variable strip mining method,namely harmonious strip mining,to effectively reduce the surface damage and the loss of coal resource,and achieve to protect the ground establishment and environment.更多还原
