摘　　要：根据济三煤矿地质条件和开采技术条件,分析确定深部六采区6303工作面具有中等冲击危险性,冲击危险指数为0.63。针对此,在6303工作面开采期间采取了煤体大直径钻孔卸压、煤体爆破卸压和顶板预裂爆破等几项技术措施,并配合采用钻屑法、电磁辐射法和钻孔窥视仪检测法对治理效果进行了检验,结果表明,几项技术措施的实施降低了煤体和顶板的冲击危险性。Based on the geological condition and mining technical condition of Jining No.3 coal mine,analysis of impact risks at 6303 mining face of No.6 depth mining district is made.The result shows that,the mining face has medium grade impact risks with 0.63 impact risk index.The key factors affecting impact risks are： big mining depth,hard and thick sandstone layer roof,coal-seam has the feature of impact orientation,structural stress and gob areas adjacent to it.Based on the above,several technical measures have been taken through coal pressure releasing by drilling big diameter holes,coal seam blasting and roof pre-cracking blasting etc.The above treating results have been proved by using drillings method,electromagnetic radiation method,and peephole inspection method.The application result shows that,the implementing of the above measures has reduced impact risks of coal and roof.
