Xinhu Coal Mine Kilometers Deputy Well -960 m Matoumen Construction Technology

摘要: 信湖煤矿副井井筒与−960 m车场连接处马头门，地压大，支护形式较为复杂，施工工作面狭窄，机械化程度低，安全风险系数较高，工序转换频繁，质量控制是施工的难点。施工单位认真组织，精心施工，达到了质量优良、安全无事故的施工目标。

Abstract: The connection of Xinhu coal mine sub-shaft and −960 m yard at the Matoumen Gate has large ground pressure, support forms are more complex, construction work face is narrow, the degree of mechanization is low, safety risk coefficient is high, the process conversion is frequent, and quality control is a difficult point in construction. The construction units are carefully organized and carefully constructed to achieve the construction goals of excellent quality and safety without accidents.
