【摘要】：為考察取樣過程中風(fēng)流對(duì)煤樣瓦斯解吸規(guī)律的影響,理論分析并實(shí)測(cè)了取樣時(shí)鉆機(jī)進(jìn)風(fēng)流參數(shù),并對(duì)影響煤樣解析規(guī)律的因素進(jìn)行了理論分析。通過試驗(yàn)研究風(fēng)流吹掃與自然暴露情況下煤樣瓦斯解吸規(guī)律,驗(yàn)證了取樣過程中風(fēng)流對(duì)煤樣瓦斯解吸規(guī)律的影響可以忽略,為煤層瓦斯含量損失量推算提供理論支撐。
[Abstract]:In order to investigate the influence of air flow on gas desorption of coal sample during sampling, the parameters of air flow in drilling rig during sampling were analyzed and measured theoretically. The factors affecting the analytical law of coal sample are analyzed theoretically. The desorption law of coal sample gas under the condition of air flow purging and natural exposure is studied experimentally, and the influence of air flow on the law of coal sample gas desorption is proved to be negligible during the sampling process. It provides theoretical support for calculating the loss of gas content in coal seam.
