摘要
为了解决低透气性煤层的瓦斯突出问题,实现矿井的安全高效生产,在不能进行上保护层开采的情况下,将近距离下保护层作为区域性瓦斯防治措施。对何庄煤矿下保护层开采的必要性进行了阐述,并介绍了近距离下保护层反程序开采可行性的评价指标。通过在11采区进行先采下解放层的反程序开采工艺研究与实践,证明了下解放层的开采是解决本矿二1煤与瓦斯突出问题的有效途径,对于豫西类似条件下的三软煤层瓦斯治理有一定的借鉴意义。
In order to solve the gas outburst problem in low permeability seam and to have a mine safety and high efficient production,when the top protected seam could no be mined,the paper stated the necessity of the coal mining in the down protected seam in Hezhuang Mine with the short distance down protected seam as the local gas prevention and control measures.The paper introduced the assessment index of the feasibility for the reversed program mining in the short distance down protected seam.The study and practi...
