摘要
以主焦煤矿合理高位钻场布置间距为切入点,在高位抽采采空区瓦斯相关研究的基础上,着重关注高位抽采措施在实际工程抽采中的连续性问题。通过分析高位抽采措施的设计思路及参数计算方式,结合实际生产中上覆岩层受开采扰动的裂隙不规则发育及动态模糊变化,确定了高位钻场合理布置间距。观测2308工作面开采过程中抽采浓度、抽采纯量的数据变化曲线,得到主焦煤矿的高位钻场合理布置间距为50 m,可为同类煤矿的安全生产提供实践经验。
Based on the previous research on the gas in the gob of high-level drainage,the continuity of high-level drainage measures in the actual engineering drainage is focused on.Based on the theoretical analysis of the design idea and parameter calculation method of high-level pumping measures,combined with the irregular development and dynamic fuzzy change of the overlying strata disturbed by mining in the actual production,the selection method of reasonable spacing of high-level drilling field is determined.Through the observation of the change curve of the extraction data of the extraction concentration and the extraction purity in the mining process of the 2308 working face,the reasonable spacing of the high-level drilling field of the main coking coal mine is 50 m,which provides practical experience for the safety production of the same type of coal mine.
