Rapid preparation method of concrete for metal mine underground guniting support
The invention relates to a rapid preparation method of concrete for underground guniting support of a metal mine, which comprises the following steps: excavating an underground concentrated guniting concrete preparation area chamber (4) near a 350m horizontal ingate (40) under a 2 # auxiliary shaft, and arranging a waste rock storage chamber (41), a stone processing area (42), a sand making chamber (43), a cement chamber (44), a concrete preparation area (45) and a water sump chamber (46) in the chamber; in the stone processing area (42) and the sand making chamber (43), waste stones generated in underground mining are processed into finished stones and sand, the finished stones and sand are conveyed to the concrete preparation area (45) and stirred by a stirrer to prepare concrete for guniting, then the concrete is conveyed to a guniting working face (47) by a mining cement tanker, and the concrete reaches the guniting working face through a mining hydraulic wet spraying trolley for wet spraying operation. The method has the advantages of improving the working efficiency, reducing the construction cost, reducing the potential safety hazard and ensuring the life health of operators.
本发明涉及一种金属矿山井下喷浆支护用混凝土快速制备方法，包括在2#副井井下‑350m水平马头门（40）附近开掘井下集中喷浆混凝土制备区硐室（4），硐室内设有废石储存硐室（41）、石子加工区（42）、制砂硐室（43）、水泥硐室（44）、混凝土制备区（45）和水仓硐室（46）；石子加工区（42）和制砂硐室（43）内将井下开采中产生的废石加工出成品石子和砂子，并运至混凝土制备区（45），通过搅拌机搅拌后制备出喷浆用混凝土，再由矿用水泥罐车运送到喷浆工作面（47），并通过矿用液压湿喷台车到达喷浆工作面进行湿喷作业。本发明的优点是提高作业效率，降低施工成本，减小安全隐患，保证操作人员的生命健康。
