The strata behavior rule of Longwall face with individual props in shallowly buried coal seam covered with thick soil was summarized. 实验和观测表明，尽管其上覆岩层的力学强度比较小，煤层埋深浅，但工作面初次来压步距大，矿山压力显现剧烈，周期来压台阶下沉量大。
As we know,CO_2 has a higher adsorbability than CH_4.If CO_2 is injected into coal seam,CH_4 can be replaced by CO_2.By using this technology,we can develop the deeply buried coal bed methane in most of our coal basins. CO2的吸附能力是CH4的4倍以上,如果把CO2通过钻井注入到深部煤层中,由于其吸附能力的差异,CH4会被优先置换出来,利用该技术一方面实现封存CO2的目的,同时还能够开发深部CH4。这种置换技术在我国很多含煤盆地具有广阔的应用前景。
