| 摘 要： | 石炭井矿区是西北重要的炼、配焦煤供应基地之一，由于生产年代长远，矿区内已面临着煤炭资源枯竭的重大问题。为使老矿区能够恢复生产活力，本文对矿区煤类变质因素在一定程度上作了分析探讨，证实矿区深部仍有大量优质煤类贮存。为了更直观的反映出煤层在上覆地层压力下挥发分变化特点，本文作出一种新型的剖面图加以说明。

| Abstract: | Shitanjing mining area is the one of important provision base of coking co al and blending coking coal in Northwestern China.Because of very long period o f production,there are serious problem on coal resources has dried up in the pr oductive area at present.In order to recover productive vigour of old min-ing area,the paper has analysed and probed into each type of coal metamorphic fact ors,for to prove still reserving large quantity and good quality of coal in the deep of mining area.In order to reflect visually change properties of volatile matter of coal under the pressure of overlying formation,a new type of sec-ti on figure made in the paper. |
