紫晟煤业“三下”压煤工作面充填开采方案研究

Study on filling mining scheme of"three lower"coal face in Zisheng coal mine

针对霍州市紫晟煤业2号“三下”压煤现状,通过现场勘查并结合具体地质开采条件提出了短壁膏体连采连充方案;对短壁膏体短壁膏体连采连充工作面进行了设计,对采充工艺、充填工艺进行了设计;针对充填体进行了变形量监测,得到变形量较小,不会对地表建筑物产生影响。

According to the present situation of 2"three lower"coal pressure in Zisheng coal industry of Huozhou City,through on-site investigation and combined with specific geological mining conditions,the short wall paste continuous mining and continuous filling scheme is proposed;the short wall paste short wall paste continuous mining and continuous filling working face is designed,and the mining and filling technology and filling technology are designed;the deformation of filling body is monitored,and the deformation is small,which will not affect the surface construction Buildings have an impact.
