Key Protecting Strata Criterion of Water Conservation Mining and its Application

Abstract:

The entironment is deteriorating increasingly in north of Shaanxi Yushenfu mine with coal mining cosmically. The causation is the lapse of groundwater owing to mining. Water conservation mining has been the exigent request. Aiming at the need of water conversation mining in north of Shaanxi shallow seam mine, this article found key protecting strata criterion of water conservation mining according as the moving law of overburden rock and the mechanics model of fixed beam. The water conservation mine method in different overburden rock mine was put forward with the condition of no destroying water protecting strata. The feasibility of the key protecting strata criterion was validated using the choice of water conservation mine method in two different overburden rock frame mine in north of Shaanxi shallow seam mine. At the time, validating the computational result applying similitude simulation test and numerical simulation. The key protecting criterion offers a theoretic computational method for the choice of water protecting mining in different overburden rock frame mine.
