Inorganic material for reinforcement
The inorganic material is prepared from, by weight, 30-90 parts of specially-made cement, 0.1-20 parts of an accelerator, 6-35 parts of stone powder, 0.4-26 part of bentonite, 0.2-10 parts of sulfate,0.1-15 parts of a water reducing agent, 0.1-18 parts of silicon-calcium powder, 0.1-17 parts of an early strength agent, 0-10 parts of fine powder, 0-5 parts of iron powder, 0.2-20 parts of fly ash and 0.3-11 parts of gypsum. A vertical anchor rod hole is drilled in a coal-rock mass by using an anchor rod drilling machine, an anchor rod is inserted into the anchor rod hole, inorganic materials are mixed according to a water-cement ratio of (0.28-0.4): 1, and grouting is performed by using the anchor rod to reinforce the coal-rock mass. The inorganic material has the effects of preventing fireand ensuring safe production of a coal mine and roadway utilization; repeated roadway repair is completely eradicated, slope deviation and roof fall are prevented, operation is easy, and safety and reliability are achieved; and the inorganic material is economical and applicable.
本发明公开了一种用于加固的无机材料，由以下重量份原料组成：特制水泥30‑90份，速凝剂0.1‑20份，石粉6‑35份，膨润土0.4‑26份，硫酸盐0.2‑10份，减水剂0.1‑15份，硅钙粉0.1‑18份，早强剂0.1‑17份，精粉0‑10份，铁粉0‑5份，粉煤灰0.2‑20份，石膏0.3‑11份；使用锚杆钻机在煤岩体中钻出竖向的锚杆孔，将锚杆插入锚杆孔中，再将无机材料按水灰比0.28～0.4:1混合，并通过锚杆进行注浆对煤岩体进行加固，本发明的无机材料具有防止着火，保证煤矿安全生产和巷道利用；杜绝巷道重复修护，防止偏帮、冒顶，操作简单，安全可靠；经济适用的优点。
