摘要
在瓦斯抽采工程中,需要施工大量的煤层钻孔。然而,由于煤层松软钻孔的成型和稳定性差,严重制约了钻孔施工和抽采的效率。通过对影响松软煤体钻孔稳定性的因素进行分析,探讨了钻孔塌孔的机理,以期为瓦斯抽采钻孔的施工提供一定的指导。
In gas drainage engineering,a large number of coal seam boreholes need to be constructed.However,due to the poor formation and stability of soft coal seam drilling,the efficiency of drilling construction and extraction is seriously restricted.By analyzing the factors affecting the borehole stability of soft coal,the mechanism of borehole collapse was discussed in order to provide some guidance for the construction of gas drainage boreholes.
