瓦斯抽采定向长钻孔智能设计方法及系统

Intelligent Design Method and System for Long Directional Gas Drainage Drilling

我国煤矿普遍采用人工"尝试逼近"的方法进行瓦斯抽采定向长钻孔设计,其效率低、精度差、设计人员工作量大,不利于矿井的安全、高产、高效。针对该技术问题,研究了兼容顺层、穿层、高位等钻孔布置方式的定向钻孔设计方法,并基于SuperMap Object.Net 6R平台开发了定向钻孔智能设计系统,实现了定向瓦斯抽采钻孔轨迹参数的自动计算和成图,为煤矿技术人员进行定向瓦斯抽采钻孔设计提供了自动化手段。在寺河矿的现场应用表明,该系统的定向钻孔单孔设计时间不超过10 min,极大地提高了定向钻孔的设计效率。

The method of artificial ＂try to approach＂ is widely used in the design of directional long gas drainage drilling in China coal mines. This method is of low efficiency, poor accuracy, and large workload, is not conducive to the safety, high yield and ef- ficiency of the mine. To solve this technical problem, the directional drilling intelligent design method which compromises bedding, layer-through, and high position is established, and the matched software system based on Super Map Object.Net 6R is developed. The system has the function of automatic design and mapping of directional drilling, provides an automatic method for the techni- cal personnel. Field application of the system in the Sihe Mine shows that the design time of the directional drilling is not more than 10 minutes, which greatly improves the design efficiency of directional drilling.
