Construction process for manufacturing closed coal mine goaf by using guniting method
The invention discloses a construction process for making a closed coal mine goaf by using a guniting method, belongs to the technical field of coal seam closed construction, and solves the problems of poor strength and air tightness and slow process making existing in brick-concrete masonry goaf closeness. The construction process comprises the following steps: performing slotting at a closed position, and then performing solid connection with a coal rock mass; connecting double-layer anchor rods and deformed steel bars at the periphery of the tank body to form a grid framework, and erecting a reinforcement framework at the center of the tank body; a water drain pipe, a measure pipe and an observation pipe are arranged on the two sides of the groove roadway respectively; the spraying operation is stopped when each closed spraying operation reaches the operation design height; carrying out guniting on the roadway outside the closed point; and a #-shaped wood crib is arranged outside the closed point, finally, the closed water drainage pipe, the measure pipe and the observation pipe are blocked, and watering maintenance is conducted every day till the concrete strength value is higher than the design standard. The method has the advantages of being rapid in construction, low in material consumption and good in sealing effect.
本发明公开了一种使用喷浆法对煤矿采空区制作密闭的施工工艺，属于煤层密闭施工技术领域，解决了砖混砌筑采空区密闭存在强度和气密性差、工艺制作缓慢的问题，本发明包括以下步骤：在密闭位置实施掏槽后与煤岩体接实；在槽体周边将双层锚杆与螺纹钢连接形成网格骨架，在槽体中央架设钢筋骨架；在槽体巷道两帮分别设置泄水管、措施管和观测管；每道密闭喷筑达作业设计高度时停止喷筑作业；将密闭点以外的巷道进行喷浆；在密闭点外打设“＃”字型木垛，最后封堵密闭泄水管、措施管和观测管，每天洒水养护，直至混凝土强度值高于设计标准。本发明具有施工快速，材料消耗少，密闭效果好的特点。
