Safety Requirements for Crossing Mining in Overlapped Areas of Oil, Gas, and Coal Mineral Rights
1 Scope
This document specifies the basic safety requirements for the cross-mining operations of oil and gas resources and coal resources within overlapped areas of oil, gas, and coal mineral rights.
This document applies to crossing mining in overlapped areas of onshore conventional oil and gas mineral rights and underground coal mining mineral rights.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
mineral rights overlapped area
The area where the planar scope of lawfully obtained oil and gas mineral rights overlaps with that of coal mineral rights.
3.2
crossing mining
A resource extraction method where exploration and mining activities for both oil/gas and coal resources are carried out simultaneously within a mineral rights overlapped area, and there exists or may exist mutual influence in terms of time and/or space.
3.3
oil and gas facility
A collective term for oil and gas wells, pipelines, stations, valve chambers, protective facilities, and related auxiliary facilities.
3.4
oil and gas well
A well drilled from the surface into an oil or gas reservoir for the purpose of extracting petroleum or natural gas.
3.5
oil and gas pipeline
A collective term for various pipelines used to transport crude oil, refined oil products, or natural gas (including long-distance transmission pipelines, gathering pipelines, gas production pipelines, etc.), valve chambers, and auxiliary systems.
3.6
petroleum and gas station
A collective term for various stations undertaking functions such as oil and gas gathering, separation, processing, metering, and pressurization.
3.7
disposal
The process of sealing, dismantling, or repurposing oil and gas facilities after all activities have ceased or when other special requirements exist.
Note: Disposal can be categorized into in-situ disposal, off-site disposal, and repurposing.

3.8
mine shaft
A vertical or inclined excavation driven from the surface to connect with underground roadways in coal mining.
3.9
roadway
A general term for horizontal or inclined excavations driven in rock or coal seams that do not have a direct outlet to the surface.
3.10
goaf
The abandoned space left after coal extraction in a working face.
3.11
working face
The working site where coal extraction operations are directly carried out.
3.12
surface subsidence basin
The area of surface movement above a goaf caused by coal mining, commonly referred to as the surface movement basin or subsidence trough. Its boundary is generally delineated by the angle of draw or the 10 mm subsidence point.
3.13
protective coal pillar
A portion of coal left un-mined, either permanently or temporarily, underground in a coal mine to protect objects (such as railways, buildings, oil and gas facilities) within the rock strata above the coal seam and on the surface.
3.14
minable coal seam
A coal seam whose thickness meets the minimum minable thickness specified by the coal industry standards.
3.15
coal mining section
The stratigraphic interval between the roof of the uppermost minable coal seam and the floor of the lowermost minable coal seam within the mining depth range specified in the coal mine's mining license.
4 General Requirements
4.1 Oil and gas extraction enterprises and coal mining enterprises shall, according to relevant national and local requirements, sign and adhere to agreements on mutual non-interference and rights protection for crossing mining in the mineral rights overlapped area.
4.2 Oil and gas extraction enterprises and coal mining enterprises shall negotiate, formulate, and adhere to a crossing mining plan for the mineral rights overlapped area. The plan shall include, but not be limited to, the following content:
