| 摘 要： | 基于对低透气性煤层顶板受采动影响下的移动规律的研究，铁法矿区于1994年通过联合国UNDP项目率先在国内应用地面垂直采空区钻井进行了技术示范。通过对已经施工的21口采空区钻井的应用和研究，铁法矿区对于采空区钻井的布孔原则和理论方面取得了丰富的经验和成果，大量的实践也证明了地面垂直采空区钻井技术在低透气性煤层，尤其在煤层群开采时，是最有效的煤层气开发技术之一。

| Abstract: | Based on research of rules of roof movement when coal seams of low permeability are extracted, Tiefa mining area undertook the first technical demonstration project supported by UNDP of drilling surface vertical gob wells in 1994. Through application and research of 21 gob wells Tiefa mining area has obtained rich experience and good results with the principles and theory of gob well patterns. A great deal of practice has also proved that the surface vertical gob well technology is one of the most effective technologies for coal seams with low permeability, especially when mining a group of coal seams. |
