兴隆煤矿汪庄矿地质构造比较复杂,煤层赋存不稳定,火成岩侵入严重,有煤尘爆炸危险,属高级瓦斯矿井。多年来,采煤方法落后,工人劳动量大,安全没有保障,煤炭丢失严重。由于煤炭回收率低,致使矿井采掘比例紧张,也直接影响着矿井的寿命。因此,改革采煤方法成为汪庄矿的当务之急。 为此,我们对金属矿山大庙铁矿的深孔爆破采矿方法和北京矿务局的伪斜短壁深孔爆破采煤方法进行了考察和学习,确定了以中深孔爆破作为主要工艺,拟定了 Xinglong coal mine Wangzhuang geological structure is more complicated, unstable coal seam, igneous rock intrusion, coal dust explosion danger, is an advanced gas mine. Over the years, backward coal mining methods, workers labor, security is not guaranteed, serious loss of coal. Due to the low recovery rate of coal, resulting in a tight proportion of mine mining, but also directly affect the life of the mine. Therefore, the reform of mining methods has become the top priority of Wangzhuang mine. To this end, we conducted a study and study on the deep-hole blasting mining method of the Daming iron mine in the metal mine and the pseudo-oblique shortwall deep-hole blasting mining method of the Beijing Bureau of Mines. We determined that the medium-deep borehole blasting is the main process, Drafted
