Constant monitoring of energy law grouting surrounding rock

,[link widoczny dla zalogowanych], Extrusion and split any type of law and the corresponding grouting parameters. Are very difficult, which often results in poor choices by type of grouting grouting result is not ideal. Constant energy method does not exist these problems, it only focus on whether the grouting PQ value, thus simplifying the problem. (4) E-PQ stationary energy method compatible with single index control grouting (limit pressure method and limit laws),[link widoczny dla zalogowanych], but it is more than a single index control grouting method is more scientific. More applicable and vitality. In addition. Steady Energy Act contains the time factor. The amount of grouting pressure and grouting time for change is a process of grouting. Qishan test mine grouting reinforcement training units to implement the three indicators of grouting grouting. In fact the steady energy method applied to the idea. (5 proved. Stationary energy method using a single indicator method than monitoring rock grouting. The grouting works much better. For example. Qishan mining depth of about 600m of a 585m track belt roadway rock bolt,[link widoczny dla zalogowanych], the original spray support. the subject of the upper coal mining within the span of roadway over broken 80. Later steady energy method by grouting the remaining front of the tunnel cross-section of mining. reinforcement, the roadway will no longer be the strong impact of mining. Its maintained in good condition. tunnel intact. but. geological conditions and mining support form with a 585m Qishan similar roadway in a mine in Huainan East roadway. in the impact of mining were not to appear to help the local film in varying degrees, Roof damage. was limited by pressure grouting method. grouting and grouting materials and their ratio of ore similar way with Qishan,[link widoczny dla zalogowanych], and then, with limited pressure Grouting, there are often run slurry leakage phenomenon. grouting after Huainan Mining Institute .15 l6 1996, No . 4 deformation of the roadway to continue to increase and maintain the state has not been significantly improved. Thus, the geological conditions and the roadway support in the form similar to the case of stationary energy use law and limited pressure grouting rock single index control, the effect of totally different case, the former than the latter better control grouting in order to achieve the purpose of maintaining roadways in good condition. 5 Summary This paper presents a scientific and broad application of the monitoring process and the end of rock grouting grouting standard stationary energy method. It is compatible with the existing limit pressure method commonly used single index or a limited control grouting method, therefore, a more steady energy method for and vitality. of steady energy method gives the control principles and elements of rock grouting. stationary energy method of monitoring the development of creative new method of grouting process.
