东庞煤矿是河北省南部最大的矿井,设计生产能力180万t/a。1983午12月26日,矿井一期工程投产,投产能力120万t/a。投产后一边生产,一边抓二期工程。 1985年,在编制矿井“七·五”发展规划时,提出要在投产四年后达到180万t/a的设计生产能力,争取1990年建成现代化矿井。为了达到上述目标,我们根据煤炭资源的赋存情况,研究了最佳开采方式。2号煤平均厚度4.42m,硬度中等,为Ⅱ类二型顶板,地质构造大部分比较简单,
Dong Pang Coal Mine is the largest mine in the southern part of Hebei Province, with a designed production capacity of 1.8 million t / a. December 26, 1983, mine a project put into operation, production capacity of 1.2 million t / a. Put into operation after production, while grasping the second phase of the project. In 1985, when formulating the “7.5 Seventh Five-Year Plan” for mine development, it proposed to reach a design and production capacity of 1.8 million t / a after four years of operation, aiming to build a modernized mine in 1990. In order to achieve the above objectives, we have studied the best mode of exploitation based on the occurrence of coal resources. The average thickness of No. 2 coal is 4.42m, with moderate hardness, which is Ⅱ type II roof. Most of the geological structure is relatively simple,
