Study Of The Comprehensive Government Of Grouting And Sealing-Up By Concrete Curtain On Caiyuan Coal Mine Auxiliary Shaft

After analyzing the granulated substance phenomenon scientifically, the thesis proposes the way of direct choking-up in the pit shaft, it seals off the Sand-running out spot directly, drills holes in the ground, and then governs the water-bearing sand by using the perforation grouting and shaft sinking way from the top downward to Solid tube partition. On the while, the author carries on the track monitoring the condition of grouting of the Caiyuan coal mine auxiliary shaft, and then examines the subsidence on the industry square of Caiyuan coal mine. It concludes that the Caiyuan coal mine obtained an excellent effect. The study of the comprehensive government of grouting and sealing-up by concrete curtain on pit shaft mainly includes: the technical design of drilling holes in the ground, grouting and sealing-up by concrete curtain, the measure of the grouting quality guarantee, the safeguard system of project quality, the system of ground drilling and grouting, the system of grouting construction and so on. The principle of the security monitoring and panalarm of the ground grouting of the shaft lining is as follows: make a reasonable arrangement of the strain monitoring spot on shaft lining, establish a mechanics model and determine the utmost stress and the state of strain by kinds of load combining effect and the coupled mechanism between load combining effect and the shaft lining, measure the data of strain and the temperature by using sensors, send the data to data warning equipment, and then read and store the data through data warning equipment, make a security monitoring to the shaft lining. The process of the security monitoring system of the pit shaft mainly contains the installment, the principle, the composition of system, the choice of the technical index, the effect analysis of the detecting. The Caiyuan coal industry square subsidence-monitoring work is using the equipment to monitor the subsidence scientifically, according to the actual coordinates by using the horizontal control survey method, determining the plane position. Through taking the comprehensive measures above, Caiyuan coal...
