➡ Down Hole Motors(DHM) are well used in directional drilling machine in coal mines; ➡Directional Drilling is the process of controlling the direction, or path, of a drill hole with the aim of either preventing deviation; ➡In-seam directionally drilled horizontal boreholes have provided effective solutions in underground coal mines for methane and water drainage; ➡Meanwhile, including the specific directional drilling and coring procedures for exploration in-advance of mining; ➡Other directional drilling applications include in-mine horizontal gob ventilation boreholes, identification of abandoned workings. ⁉ So How to adjust the drilling direction in hole? Use the downhole tools like a bent sub or a mud motor to change the direction of the drill bit. Mud Motors can be with fixed bend housing, or the adjustable bend housing(ABH 0-3degree); When set one different bend degree, this to reposition the bit to the desired trajectory. When it starts drilling again, the pilot drill bit starts going in the direction that it’s now pointing towards. #coalmine #coalmining #geotechnicalboreholedrilling #Mine #siteinvestigation #Majordrilling #mining #coalminedrilling #mineralexploration #exploration #undergroundmining #groundinvestigation #geothermal #miningequipment #explorationdrilling #metalsindustry #DiamondDrilling #UndergroundDirectionalDrilling #drilling #drillandblast #blasting #Boreholedrilling #pilotdrilling #directionaldrilling #miningexplorationprojects #miningoperations #boreholetechnology #DHM #DownholeMotor #drillingmotor #drillbit #PDCbit #Corebit #diamondimpregnateddrillbits #PDCreamer #rockcrossing #hardformation #highspeedmudmotor #hightempeturemudmotor #CTmotor #bigtorquemudmotor #Hardrubber #highperformancerubber #downhole #energy #DownholeTechnologies #drillingequipment #navigationaldrilling #drillingtools #drillingmud #downholetools
