摘要
某矿150506工作面开采属于多煤层重复开采,控制地表村庄等建筑物变形是采矿业迫切需要解决的难题之一,本文通过条采下沉系数、拐点偏距、主要影响角正切、水平移动系数经验计算得到三种回采方案下的地表移动与变形特征参数,为工作面安全回采优选了条采方案。
A mine 150506 mining belongs to coal repeated mining,control surface Village building deformation is one of the mining industry is an urgent need to solve the problem,this paper by strip mining subsidence calculation coefficient,inflection point offset,main angle tangent,horizontal movement coefficient experience obtained three kinds of mining method of surface movement and deformation characteristic parameters,work safety mining optimized strip mining scheme.
