随着我国煤矿机械化水平的不断提高和煤炭科学技术的不断进步,矿井的开拓部署也随之发生了一系列的变化和改进。根据我院对两淮及其邻近矿区部分矿井的设计回访和实地调查,结合两淮矿区的特点,现对两淮矿区矿井的开拓部署改革作以下分析和探讨。 一、两淮矿区概况 两淮矿区是我国重要煤炭基地之一,区内有可采煤层6～16层,可采总厚度淮北为9～21m,淮南24～32m,地质储量总计约226亿t。淮北煤的品种较全,有焦煤、肥煤、气煤等,其中以气煤为主,主要作为炼焦用煤。淮南煤的牌号单一,主要以气肥煤
As China’s coal mine mechanization level continues to improve and the continuous improvement of coal science and technology, mine development and deployment also followed a series of changes and improvements. According to the design review and site investigation of some coal mines in the two Huai and neighboring mines and the characteristics of Lianghuai mining area in our hospital, we will make the following analysis and discussion on the reform and opening up and deployment of coal mines in the Huainan and Huainan mining areas. I. Overview of Lianghuai Mining Area Lianghuai mining area is one of the important coal bases in our country. There are 6 to 16 layers of coal seam in the area. The total recoverable thickness is from 9 to 21m in Huaibei and from 24 to 32m in Huainan and the total geological reserves are about 22.6 billion t. Huaibei coal varieties more complete, coking coal, fat coal, gas coal, etc., of which mainly coal gas, mainly as coking coal. Huainan coal single brand, mainly to gas fat coal
