Research on the Effective Influence Radius of Hydraulic Reaming in Mining Seam
According to the present situations that the construction amount of the gas drainage boreholes in mining seam is large and the gas drainage effect in low permeability coal seams doesn’t yield perfect, the hydraulic reaming technology in mining seam is proposed to increase the gas drainage efficiency. Through the gas flow method, the effective influence radius of hydraulic reaming is determined....
متن کاملOptimization of Drilling Layouts Based on Controlled Presplitting Blasting through Strata for Gas Drainage in Coal Roadway Strips
The controlled presplitting blasting technique is widely used in mining engineering to improve the permeability and gas extraction efficiency of coal seams. One of the key factors is the appropriate arrangement of the blasting and drainage holes, which can help improve the gas drainage quantity. To optimize the drilling layout to enhance gas-drainage efficiency, a series of controlled presplitt...

15 صفحه اولa gender-based pragmatic analysis of the use of english compliment responses by iraqi efl students:a speech act perspective
تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...
Influence of DEM interpolation methods in Drainage Analysis
The accuracy of the Digital Elevation Models (DEMs) interpolated using four different methods was compared in two small watersheds in the Ecuadorian Andes. The interpolation methods compared were Inverse Distance Weighted, radial basis functions, ordinary Kriging, and TOPOGRID. A qualitative comparison was made between the stream network modeled in Arc Hydro and the digitized stream network. Mo...
