本文是关于S1201工作面定向水力压裂初次放顶工作的总结,从工作面概况、工作面定向水力压裂、初采过程中的顶板动态及压力情况和与工作面初采顶板欲裂爆破技术对比等方面对于此次放顶工作进行了多方面的分析,进而得出定向水力压裂技术在S1201工作面顶板初采初放中应用效果良好,值得在类似煤层地质条件中推广应用的结论,除此之外,也提出了在这项技术使用过程中应该注意的问题,以此减少企业损失。
This article is a summary of the initial top caving work of directional hydraulic fracturing in S1201 workface. From the general situation of the working face, directional hydraulic fracturing in the working face, the dynamic and pressure conditions of the roof in the initial mining process and the blasting blasting technology Contrast and other aspects of the caving work conducted a multi-faceted analysis, and then come to the directional hydraulic fracturing technology in S1201 working face roof initial application in good effect, it is worth in similar geological conditions of the coal to promote the application of the conclusion, In addition, problems that should be noticed during the use of this technology are also proposed to reduce business losses.
