摘　　要：受开采条件限制,部分综采工作面开采长度设计时须进行延伸,回采通过延伸段及贯穿整个工作面老巷,成为制约综采工作面安全生产的主要因素之一。通过图纸模拟及分析,提出了综采工作面过延伸段、贯穿整个工作面老巷关键技术及现场管理重点,并对类似工作面设计提出了改进建议。现场实践及论证表明,综采工作面涉及二次延伸及为解决通风问题须设计贯穿中部运输、回风巷之间的联络巷时,杜绝与二次延伸段设计在同一位置;通过延伸段及中部措施巷时必须对特殊地段进行补强支护,以防采动、周期来压影响导致巷道冒落或综采支架通过老巷时出现支架压死等现象;通过中部措施巷及延伸段时,必须对作业顺序、工程量、劳动组织等进行全面安排,避免交叉作业导致工作混乱。Due to the restriction of mining conditions,part of the length of fully mechanized mining face must be extended in the design,and the mining through the extension section and through the used roadway of the whole face has become the main factor restricting the safety production of fully mechanized mining face.Through drawing simulation and field practice analysis,the key technology and site management of the over extension section and through the whole used roadway of fully mechanized mining face are put forward,and the improvement suggestions for similar working face design are given.Through the analysis and field demonstration,it is shown that:when the fully mechanized mining face involves secondary extension and the contact roadway between the central transportation and return air roadways must be designed to solve the ventilation problem,it should not be designed in the same position with the secondary extension section;Reinforcement support must be carried out in the special section when passing through the extension section and the central measure roadway to prevent the caving of roadway or the crushing of fully mechanized mining support passing through the used roadway under the influence of mining and periodic weighting.When passing through the middle measure roadway and the extension section,it is necessary to make a comprehensive arrangement of the operation sequence,engineering quantity,labor organization,etc.,to avoid the confusion caused by cross operation.
