TECHNOLOGY STUDY OF ADHESIVE TAPE DRAINAGE ROCK IN LARGE OPEN-PIT MINES

The paper makes a detailed technology study of adhesive tape drainage rock in large open-pit mines, including forming method of first embankment, way and method of drainage rock, moving process of adhesive tape and process method of "dead area" etc. On the basis of different way and method of drainage rock, the calculate formula of drainage rock parameters have been put forward, as an example of Da Gushan mine, drainage rock parameters have been determined.
