摘要
梅林庙井田范围内有哈头才当一级水源保护区。为了保护水资源,开发出6 m大采高年产千万吨工作面非胶结膏体充填开采技术。该技术不仅保护了水资源,还可以处理矸石,取代采空区灌浆防灭火系统,实现绿色开采。
The Hatoucaidang first-grade water source protection area is located in Meilinmiao minefield. In order to protect water source,6m large mining height mining technology of non cemented paste filling was developed in working face with an annual output of ten million tons. This technology can protect water source,deplete coal gangue,replace the grouting fireprevention system in goaf and realize green mining.
