Brief analysis of floor grouting method in soft rock roadway based on engineering materials and engineering mechanics Pengwei Hao1,2,a, Hailong Dong2,b, Zhaohui Liu1,c, Jingpei Li1,d, Laiwang Jing2,e 1 School of Civil Engineering and Mechanics, China University of Mining and Technology (Beijing), Beijing, China, 10083 2 College of Science, Anhui University of Science and Technology, Huainan, Anhui, China, 232001 a57066490@qq.com, b824426446@qq.com, clzh4969183@163.com, dLijp6666@126.com, elxybg@aust.edu.cn Key words: soft rock roadway, floor grouting, broken rock zone, free water in floor Abstract: Floor grouting in soft rock roadway is one of the effective ways in floor heave control, and this method is being promoted quietly and quickly, but the applying effect is far from satisfied, the reasons are that: the depth of floor grouting is not enough and the influence of water hiding in floor hasn’t been attached great importance.
The three hinged beams A, B, C and the three points a, b, c, to rock like materials, if they exist or not will not greatly affect the stress distribution of surrounding rock ,that is, the result obtained what is based on circular roadway analysis is relatively accurate, so it can be used as main basis of roadway support design.
It makes free water be drained away from floor, so floor broken rock zone would not further expand any more because of water soak. 4 Difficulties analysis of floor grouting The materials and mechanical devices used in floor grouting are essentially the same as those used in roof grouting, but floor broken rock zone is the deepest, furthermore there is a lot of free water in it.

Material and Method Feed Materials.
Table 1 shows the characteristics of feed materials.
Total solid (TS), volatile solid (VS), total carbon (TC) and total nitrogen (TN) of feed materials were measured before and at the end of digestion period.
The high initial biogas production attributed to the preferential digestion of readily biodegradable organic materials like carbohydrates.
The dissipation of the readily biodegradable organic materials may have caused temporary biogas production decrease subsequently.

Recently, the γ-Fe2O3 attracted the interest to use as gas-sensitive materials in the field of environment protection [2].

Zinc metallurgical materials with high strength, good damping, and low manufacturing cost, is very potential to be the high temperature soft lead-free solder, however, the wettability of zinc base solder is poor, to some extent, which makes its application is limited .
In recent years, Advanced connection materials group of Henan university of science and technology has developed a new type of zinc metallurgical flux, which can effectively improve wettability of zinc filler metals.
