随着我国经济的高速发展,国家对铝土矿资源的需求越来越大,但是经过近几十年的开采,赋盖层较浅的铝土矿资源已较少,所以铝土矿地下开采是我国今后铝土矿开采的主要发展方向。由于煤与铝土矿伴生的特点,很多地层中伴有煤层,因此矿山在采掘过程中有可能穿过煤层,如果煤层中瓦斯没有得到提前释放,就可能涌入矿井,使矿井成为瓦斯矿井,从而增大铝土矿地下开采的难度和危险性。目前我国铝土矿地下开采技术条件尚不成熟,因此,加强对铝土矿地下开采的安全管理工作显得格外重要。本文将以贾家洼西矿为例,通过对其风险进行辨识、分析,并提出控制措施,探讨如何做好地下铝土矿开采的安全管理工作,以期为读者提供借鉴。
With the rapid economic development in our country, the demand for bauxite resources in our country is getting larger and larger. However, after a few decades of exploitation, there are fewer bauxite resources with lower cover, so underground mining of bauxite It is the main development direction of bauxite mining in our country. Due to the accompanying characteristics of coal and bauxite, many formations are associated with coal seams. Therefore, the mine may pass through the coal seam during the excavation process. If the coal seam is not released in advance, it may flow into the mine and make the mine into a gas mine. Thus increasing the difficulty and danger of underground mining of bauxite. At present, the technical conditions for underground mining of bauxite in China are not yet mature, so it is especially important to strengthen the safety management of underground mining of bauxite. Taking Jiajiawa West Mine as an example, this paper will identify and analyze its risks and put forward control measures to explore how to do safety management of underground bauxite mining so as to provide reference for readers.
