摘要
华丰井田巨厚坚硬砾岩覆盖层下采煤引起的矿井顶板冲击地压及地表斑裂现象，已严重危及矿井安全并使地表农田遭受较大破坏，是目前矿井需要解决的突出的工程技术问题。本文在分析开采的地质环境特征的基础上，探讨了冲击地压及地表斑裂产生的机理，提出了相应的防治措施。
The pressure bump and Surface breaks caused by mining under the extra-thick and solid covering stratain Huafeng Colliery had been seriously, imperiling the safty of mining and had damaged plenty of farmland. In this paper, on the base of analysing the geological environment and the mining condition of Huafeng colliery, the mechanism of pressure bump and surface breaks have been discussed and the authors give some countermeasures about these problems.
