METHOD DEVELOPMENT steeply dipping ore bodies instability ores

摘要

1. Method of developing steeply dipping ore bodies with unstable ores comprising separation deposits and layers on the panel with the notch their stope in descending order and the subsequent laying of hardening mixtures, characterized in that the parameters of the stope layer is increased in height and width to the dimensions of the chamber, and the length they are divided into sections, wherein the camera-stope and sections in vertical longitudinal section shaped into an isosceles trapezium, their refinement then carried out stepwise so that at working level of each subsequent section to stavochnogo horizon is lowered to a height sectional haul generation, which, originally, in the roof of the chamber-stope for all its sections are common brown stowing production and sectional the delivery formulation for each successive section, tested under the filling mass previously spent section, wherein after full mining subsequent sections, the delivery sectional its production in the retreating manner to expand the width of the previously laid down section, wherein the direction of mining zahodok-chambers at each subsequent nizhel ezhaschem layer in the exchange to protivopolozhnoe.2. A method according to claim 1, characterized in that the delivery bookmark generation is performed simultaneously with each of the exhaust sections, and brown-stowing - simultaneously - the last section of the waste in the chamber-stope.
