鐵礦崩落法與充填法對(duì)比分析專題論文

摘  要

金山店鐵礦的主要采礦方法為無(wú)底柱分段崩落法，該采礦方法的特點(diǎn)以崩落圍巖進(jìn)行地壓管理。隨著科學(xué)技術(shù)的進(jìn)步，充填法已成為高效采礦方法之一，并且具有安全、回采率高、對(duì)地表生態(tài)環(huán)境破壞較小等一系列不可替代的優(yōu)點(diǎn)。加上充填采礦法的許多復(fù)雜的工藝實(shí)現(xiàn)了機(jī)械化和自動(dòng)化，運(yùn)用起來(lái)變得日益簡(jiǎn)單。充填采礦法將成為地下礦床開(kāi)采中一種最主要的采礦方法。本文主要通過(guò)介紹崩落采礦法和充填采礦法，并結(jié)合國(guó)內(nèi)相關(guān)研究單位對(duì)金山店鐵礦地下開(kāi)采條件的科研成果，完成金山店鐵礦崩落法與充填法對(duì)比分析。主要是根據(jù)金山店的礦體條件與兩大類采礦方法的適用條件來(lái)進(jìn)行對(duì)比分析，得出金山店鐵礦的主要采礦方法還是應(yīng)該以無(wú)底柱分段崩落法為主要采礦方法，便于從技術(shù)和生產(chǎn)上進(jìn)行管理。但是應(yīng)該根據(jù)某些礦體賦存條件采用合適的采礦方法，如采用充填采礦法來(lái)合理生產(chǎn)。

Abstract

     The major mining method of Jinshandian iron ore is the non-pillar sublevel caving, this mining methods' characteristic comes down the adjacent formation to carry on the geostatic pressure management. With the progress in science and technology has become a highly efficient method of filling one of the methods of mining, and has safe, high recovery rate of surface damage to the ecological environment, such as a series of small advantages can not be replaced. Filling mining method combined with the many complex processes in the mechanization and automation, it has become increasingly simple to use. Filling mining method will be the exploitation of underground deposits of a major method of mining. In this paper, by introducing and filling Caving mining method, combined with research units of domestic iron ore Jinshandian underground mining conditions of scientific research, the completion of caving Jinshandian iron comparative analysis with the filling method. Mainly based on the ore body Jinshandian two major categories of conditions and the application of mining methods to a comparative analysis of conditions, drawn Jinshandian iron ore is the main mining method should be based on non-pillar sublevel caving mining method primarily for from technology and production management. However, it should be in accordance with the conditions of occurrence of certain ore mining to use the appropriate methods, such as filling mining method used to produce reasonable.

Key words：Jinshandian Iron Mine;  Caving method;  Filling Method;  Mining method;   Decent production
