Description
Technical Field
The invention relates to a geological drilling method, in particular to a drilling-slope-adjustable drilling method without a drilling tower.
Background
Geological and mineral exploration and engineering geological exploration are usually completed by adopting a core drilling machine, and inclined hole drilling problems can be encountered in the actual operation process.
When the existing core drilling machine is installed and used, firstly, the drilling position needs to be determined, the field is leveled, the drilling tower is assembled, a crown block pulley of the drilling tower is positioned above the central line of the drilling hole, and then the vertical shaft of the drilling machine is adjusted to be aligned with the hole position. If the technical requirement of drilling inclined holes is met, drilling can be performed only after the angle of the vertical shaft is adjusted and fixed within 30 degrees (namely, the adjustment amount based on the vertical line is +/-30 degrees), if the adjustment angle of the vertical shaft exceeds 30 degrees, the drilling-down and drilling-up processes can be blocked, and the adjustment angle of 30 degrees cannot meet the geological exploration requirement under all scenes.
In order to solve the problem that the drilling angle of the conventional drilling machine is small in adjustment amount, a crawler-type truck-mounted drilling machine is researched and developed in the industry, and is characterized in that a drilling tower can be adjusted within 45 degrees (namely, the adjustment amount based on a vertical line is +/-45 degrees). At present, exploration tasks with special requirements such as geological prospecting, mountain-crossing expressways, railway tunnels and the like are usually performed on steep mountains, but the maximum climbing angle of the crawler-type vehicle-mounted drilling machine is only 30 degrees, the crawler-type vehicle-mounted drilling machine is not suitable for mountain operation and is difficult to enter a drilling position, the selling price of the crawler-type vehicle-mounted drilling machine is usually more than 10 times that of a common rock core drilling machine, and the application and popularization of the crawler-type vehicle-mounted drilling machine are greatly restricted.
