The article deals with the issue of planning the development of mining operations in the context of a changing demand for iron ore products. One of the problems regarding iron ore deposit mining at the current stage of open mining development presented in this work. It includes the following: mines operate with a constant operational capacity while iron ore products price and demand significant variation is observed in mineral markets. In these conditions, there is a possibility of a significant increase in economic efficiency of mining due to the implementation of a flexible change in the main parameters of the open-pit, which is achieved by a justified correction of the development of mining operations by changing the dimensions, parameters and design of the active part of the working area in an open-pit. A technique for planning the development of mining operations in an open-pit has been developed, which differs from the known ones by the possibility of regulating the main parameters of the open-pit under conditions of a changing demand for iron ore products, and also takes into account the interrelationship of mining method parameters ensuring a basic ore stock ready for excavation in the open-pit.

原料市场不完全确定条件下矿业发展战略形成的动态因素

本文讨论了在铁矿石产品需求不断变化的背景下规划采矿作业发展的问题。这项工作提出了现阶段露天采矿开发中铁矿开采的问题之一。它包括以下内容：矿山以恒定的运营能力运营，而铁矿石产品的价格和需求在矿产市场上观察到显着变化。在这些条件下，通过对露天矿的主要参数进行灵活的改变，有可能显着提高采矿的经济效益，这是通过改变采矿作业的发展来合理修正来实现的。露天矿工作区活动部分的尺寸、参数和设计。已经开发出一种规划露天采矿作业发展的技术，该技术与已知技术的不同之处在于，可以在铁矿石产品需求变化的情况下调节露天采矿的主要参数，并且考虑到采矿方法参数的相互关系，确保在露天开采时有基本的矿石储备。
