The Applications of Dynamic Grouting Technology in Ultra-Deep Shaft Wall

Abstract:

With the growth of the national economy, the social demand for coal resources is increasing. In order to maintain the sustainable development of the national economy, we must develop the deeper and wider coal layers. In deep mine construction and in the process of extending shaft downwards, we often encountered with soft rock zones and rock fracture zones where were often subjected to floods. Grouting technology is one of the most effective and reliable method to deal with water in the mine. But the traditional grouting method could not reach the good effect in plugging water. According to the local engineering practices and experiences, the new method we have mentioned above takes better effect in dealing with the problem of water permeation in ventilating shaft of Niaoshan coal mine.
