Environment-friendly grouting material based on red soil in Wumeng Mountain area

Abstract

The invention discloses an environment-friendly grouting material based on red soil in a Wumeng Mountain area. The environment-friendly grouting material based on the red soil in the Wumeng Mountain area is CL-C type clay cement paste, and the CL-C type clay cement paste is composed of clay paste, cement and additives. The environment-friendly grouting material based on the red soil in the WumengMountain area is good in past stability, the paste is not separated or precipitated in pumping and diffusion processes, and in a solidification process, the water bleeding is little, the concretion rate is high, and the anti-permeability performance is good. Clay particles in the clay paste are fine, are low in sand content, and have a high dispersion degree, so that the environment-friendly grouting material based on the red soil in the Wumeng Mountain area is good in fluidity and easily permeates into fine cracks of rock stratums. In a Maoping lead-zinc ore 112-line vertical shaft pre-grouting water-plugging engineering of the Yiliang Chihong mining limited company, 15189.132 m<3> of clay cement paste prepared from the environment-friendly grouting material provided by the invention is injected, and the residual water burst amount of the well shaft after grouting is about 4.83 m<3> / h and meets the qualified standard of a construction contract.

Description

technical field [0001] The invention relates to the field of mine survey and mine construction engineering technology under the geological conditions of the Wumeng Mountain area. Specifically, it is an environmentally friendly grouting material based on the laterite in the Wumeng Mountain area. Background technique [0002] The Wumengshan area is located at the junction of the Yunnan-Guizhou Plateau and the Sichuan Basin, including 38 counties (cities, districts) in the adjacent areas of Sichuan, Guizhou, and Yunnan provinces. The mountains are high, the valleys are deep, and the terrain is steep. Warm temperate plateau monsoon climate, uneven distribution of precipitation in time and space. The rivers in the area are vertical and horizontal, spanning the Yangtze River and the Pearl River. The Jinsha River, Minjiang River, Chishui River, Wujiang River and other Yangtze River systems are developed; the Nanpan River and Beipan River flow into the Xijiang River, which is an im...

Problems solved by technology

[0003] In the process of resource exploration and development in the Wumengshan area, problems such as large groundwater volume, high water pressure, many faults and broken zones, and complex geological conditions have been encountered; although the grouting water blocking and grouting reinforcement technology is the solution However, the current grouting material is mainly cement slurry. In the process of grouting water blocking and grouting reinforcement for mine exploration and mining in Wumeng mountainous area, there is a problem of poor water blocking effect and gushing. When the amount of water is large, it cannot play the role of grouting reinforcement and water control well
