随着矿井现代化步伐的加快,原来的π型梁单体柱的二梁五柱工作面支护已不满足矿井安全生产,悬移支架取代二梁五柱支护,增加工作面的安全系数,降低劳动强度,增加煤矿效益,对地质条件复杂矿井的替换π型梁单体柱的二梁五柱提供一种可行性办法。
As the pace of mine modernization accelerates, the original two-beam and five-column face support of π-beam single column has not met the mine safety production. The suspension bracket replaces the two beams and five columns to support, increases the safety coefficient of the working face, reduces the labor intensity, Increase the efficiency of coal mines, and provide a feasible method for replacing two beams and five columns of π-type beam monolithic columns in complex geological conditions.
