浅析软煤层中顶层综采工作面回采初期技术管理

Technology Management in the Preliminary Stage of Recovery of Fully Mechanized Working Face in the Soft Coal Seam

目前正处于煤炭行业的寒潮时期,各地煤炭企业亏损严重。为了响应国家的安全生产方针,煤炭企业在该时期生产过程中安全方面更不敢出一丝的问题。由于综采工艺相比其他采煤工艺而言大大提高了施工人员的安全系数。所以,综采工艺往往是工作面回采的首选。河南能源化工集团焦煤公司中马村矿同样采用了综采工艺对211021工作面进行回采。211021综采工作面为顶层工作面,并且所采煤层煤质较软,初采初放期间遇到了三条断层。下面就211021综采工作面回采初期的技术管理进行简要的分析总结。

Now, the coal industry is in a cold period, the loss of coal enterprises in various regions is serious. In order to respond the state policy of safety production, the coal enterprises can＇t have any safety problems in production process during this period. Compared with other coal mining technologies, fully mechanized coal mining greatly improves the safety coefficient of construction personnel. So, fully mechanized coal mining often is the first selection of mining face. Zhingmacun Mine of Jiaozuo Coal Group of Henan Energy and Chemical Industry Group Co., Ltd. uses fully mechanized coal mining to carry out the recovery of working face 211021. Working face 211021 is the top working face of fully mechanized, and the coal seam of it is softer. It meets 3 faultages in the iriitial mining and discharging. This paper will briefly analyze and summarize technology management in the preliminary stage of recovery of fully mechanized working face 211021.
