Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] The present invention provides a technical solution: a drilling process for skarn-type iron ore in thick overburden areas, comprising the following steps:

[0016] S1. Lock the drilling and verification well position, and conduct geological exploration on the well position;

[0017] S2. Conduct research on the geological data of the well location and judge the drillability, and set up the drilling equipment;

[0018] S3. Perform pre-curing treatment around the drilling...

Abstract

The invention discloses a skarn type iron mine drilling technology for thick-covering areas. The technology includes the steps that a drilling tested well site is locked and is subjected to geology exploration; geological data of the well site is investigated and surveyed and estimated whether to drill or not, and drilling equipment is erected; pre-solidification treatment is performed around thedrilling site; and shaft-drilling is performed. The skarn type iron mine drilling technology for thick-covering areas has great significance in searching high-grad iron ore deposit, the areas possiblycontaining of high-grad iron ore deposit are locked, drilling exploitation is performed, the space model of the high-grad iron ore deposit is analyzed and determined, and the technology has great advantages for searching the high-grad iron ore deposit.

Description

technical field [0001] The invention relates to the technical field of drilling technology, in particular to a drilling technology for skarn-type iron ore in thick overburden areas. Background technique [0002] Drilling refers to the use of drilling rigs to drill holes underground, take out soil or cores for analysis and research, and obtain cores and ore samples from different depths in the drill holes for analysis and research to identify ore bodies or Dividing the strata and determining the geological conditions of the strata usually account for at least 40% of the cost of drilling in geological prospecting. The diameter of the borehole is small (46-91 mm), and the depth ranges from tens of meters to several thousand meters. [0003] At present, there is no specific and complete drilling process in the exploration of skarn-type iron deposits, so a drilling process for skarn-type iron deposits in thick overburden areas has been invented. Contents of the invention [0...
