Legal Definitions - latching

Latching refers to the specialized process of conducting a survey within an underground environment, most commonly associated with mining operations. It involves precisely mapping subterranean areas to determine locations, dimensions, geological features, and the layout of tunnels, shafts, and other underground workings.

Here are some examples illustrating the application of "latching":

• Example 1: Mine Expansion Planning

  A large copper mining company plans to extend an existing ore extraction tunnel deeper into the earth to access new mineral deposits. Before any new excavation can begin, a team of surveyors is tasked with accurately mapping the current tunnel system, identifying geological strata, and plotting the precise trajectory for the new extension. This detailed mapping ensures the safety of future operations and adherence to engineering plans.

  This scenario demonstrates "latching" because it involves a comprehensive survey of the underground mine workings to inform and guide the expansion of subterranean infrastructure.

• Example 2: Resolving Boundary Disputes

  Two adjacent mining companies, "Summit Minerals" and "Deep Earth Resources," hold claims to neighboring mineral rights. A dispute arises when Summit Minerals suspects Deep Earth Resources has inadvertently extended one of its underground drifts (horizontal passages) beyond its legal boundary, encroaching on Summit's territory. To resolve the conflict, an independent surveying firm is hired to conduct a precise mapping of the underground boundaries and workings of both companies' operations.

  The independent firm's work to accurately map the underground drifts and determine the exact subterranean boundary lines between the two mining claims is an act of "latching," as it is a critical survey of the mine's underground environment.

• Example 3: Post-Incident Safety Assessment

  Following a minor collapse in a section of an underground coal mine, safety regulations require a thorough assessment of the affected area before workers can re-enter. A team of mine surveyors conducts a detailed survey of the damaged tunnels and chambers to assess structural integrity, identify any new hazards, and ensure the stability of the surrounding rock formations. This survey helps determine if the area is safe for remediation and future operations.

  This situation illustrates "latching" because it involves a meticulous survey and mapping of a specific underground section of the mine to evaluate safety conditions and structural soundness after an incident.
