（1）钻场的定位原则
①钻场间距应与钻机能力匹配.
②钻场位置宜选在确保施工的钻孔能有效定位于工作面上隅角顶板裂隙区的位置,并有足够的可抽放钻孔长度,一般在回风巷内侧.
③钻场避免布置在岩石破碎带.
（2）钻场的施工参数钻场净深度超过6m时,要采取局部通风措施,防止瓦斯积聚.钻场具体施工参数是：先在风巷下帮向煤层顶板以30°爬坡施工长×宽×高=6.0m×2.5m×2.0m的巷道,再变平施工长×宽×高=4.0m×3.5m×3.5m的卧钻平台.

(1) drilling field positioning principle
(1) drill spacing should be matching with ability to drill.
(2) the drill field location should be chosen in construction of drilling to ensure that the effective positioning in the Angle of roof fracture zone on the working plane location,and have enough length of drainage borehole,generally in return air lane inside.
(3) avoid drilling field layout in rock fracture zone.
Games (2) the drill construction parameters of the drilling depth of the net more than 6 m,local ventilation measures should be taken to prevent the gas accumulation.Drill site specific construction parameters is:under the wind lane first help to the coal seam roof with 30 ° climbing construction length x width x height = 6.0 m x 2.5 m x 2.0 m of the roadway,and flatten the construction length x width x height = 4.0 m x 3.5 m x 3.5 m lie the drilling platform.
