Chapter 2 Regulations on the Storage of Gunpowder and Explosives
Article 2.0.1 The storage quantity of underground and earth-covered gunpowder and explosive warehouses shall be based on TNT, and other gunpowder and explosives shall be converted according to the TNT equivalent value in Appendix 2. Article 2.0.2 All kinds of gunpowder and explosives should be stored in separate warehouses. However, when conditions are limited, the following gunpowder and explosives can be stored in groups: 1. RDX, Octogen, Tejieer, Taian, high-energy mixed explosives; 2. No. 4 explosives:
3. Colloidal explosives;
4. TNT, TNT, powdered ammonium nitrate, dinitronaphthalene, DNT; 5. Black powder;
6. Single-base gunpowder, double-base gunpowder;
7. Emulsion explosives, water gel explosives.
Article 2.0.3 The storage conditions of underground warehouses should meet the following requirements: 1. The ratio of the cross-sectional area of ​​the charge to the main cavern (K) should be less than or equal to 0.26, K. It should be calculated according to the following formula:
S——the measured cross-sectional area of ​​the charge (m2);
Sa——the measured cross-sectional area of ​​the main cavern (m). 2. The charge length-to-diameter ratio (KL) should be less than or equal to 18. KL should be calculated as follows: K = stack,
where L is charge length (m);
D is charge equivalent diameter (m).
3. The spacing between stacks in the warehouse should not be less than 0.1m, the width of the transport path in the warehouse should not be less than 1.2m, and the width of the inspection path along the wall should not be less than 0.7m. 4. The stacking height of various gunpowders and explosives should not exceed the provisions of Table 2.0.3. Height limits for stacking various gunpowders and explosives

Chapter III Overall Layout
Section I Site Selection
Article 3.1.1 When selecting the site for a rock cavern, the following requirements should be met in terms of topography and geology:
1. The mountain where the cavern is located should be high and thick, with a complete mountain shape and no large geological structure; 2. There should be little groundwater, and no harmful gases and radioactive substances in the rock mass. Article 3.1.2 When selecting the site of loess cave storage, the following requirements should be met in terms of topography and geology:
1. The selected valley should be stable, with intact soil and no groundwater; 2. The soil layer entering the cave should be late Pleistocene (Q3) Malan loess and middle Pleistocene (Q2) Lishi loess;
3. The rainwater catchment area upstream of the storage site should be small to avoid sudden flood hazards during the rainy season.
Article 3.1.3 When selecting the site of covered soil storage, the following requirements should be met in terms of topography and geology:
1. The storage site should be in a shallow mountain area or deep hilly area; 2. The storage site should not be selected in a landslide area where prevention and control measures are difficult and a ditch-capacity area where mud and rock flows pass through.
Section 2 Layout Principles
Article 3.2.1 The storage area, transfer station and destruction site for storing gunpowder and explosives are all dangerous areas. During the overall layout, the dangerous area and the non-dangerous area must be strictly separated and should not be mixed.
During the overall layout, the flow of people in the living area of ​​the storage area and nearby residential areas should not pass through the dangerous area: it is not advisable to allow the roads for transporting gunpowder and explosives to pass through the living area.
Section 3 External Safety Permissible Distance

1. For rock caves on gentle slopes, the maximum value of the three safety permissible distances of blasting flying rocks, explosion air shock waves, and explosion seismic waves shall be determined; 2. For rock caves and loess caves on steep slopes, the maximum value of the two safety permissible distances of explosion air shock waves and explosion seismic waves shall be determined; 3. For earth-covered warehouses, the safety permissible distance of explosion air shock waves shall be determined. Article 3.3.2 For rock caverns under gently sloping terrain conditions, when the explosive storage conditions meet the requirements of Article 2.0.3 of this Code, the external safe allowable distance for flying rocks from explosions shall comply with the following provisions:
, 1. When the angle of the protected object on both sides of the cave axis is less than or equal to 50°, it shall not be less than the provisions of Table 3.3.2-1;
