新阳煤矿采用矸石和粉煤灰充填开采综合机械化采煤技术来解决村庄下压煤开采问题。为解决不稳定顶板下开采充填,研制了ZCY7200/16/26型两柱掩护式充填液压支架对采煤与充填工作空间顶板进行有效支护。模拟结果表明,该充填液压支架可靠性高,操作简单,满足矿井充填与开采工艺互不影响的要求,在充填效果良好的情况下,破坏等级为Ⅰ级,满足房屋使用要求。
Xin Yang Coal Mine using waste rock and fly ash mining mechanized mining technology to solve the problem of coal mining under the village. In order to solve the unsteady roof under the mining filling, ZCY7200 / 16/26 type two-column cover type filling hydraulic support was developed to effectively support the roof of coal mining and filling work space. The simulation results show that the filling hydraulic support has high reliability and simple operation, meets the requirements of mine filling and mining without interfering with each other. Under the condition of good filling, the damage grade is grade Ⅰ, which meets the requirements of house use.
